Find your trainer.

Find Your Trainer is a new online marketplace which is revolutionizing the personal training industry in a similar way to how OpenTable, ZocDoc and AirBnB are transforming how we reserve restaurants, find doctors and travel. Find Your Trainer helps its customers to "get fyt" by letting them effortlessly search, book and pay for high quality and affordable personal training sessions at top gyms and studios without a gym membership, or in-home anytime, from anywhere.

The Challenge

The client needed qualified developers with extensive knowledge and previous experience on "Product Building" and "Software Maintenance". Devsar was first contracted in order to maintain their existing platform which was built by another offshore IT team. We were responsible for the Frontend and Backend of the product. As a result of that initial project, Devsar became the main contractor and finally took over the full management of the product.

The Solution...

Feastly

Feastly is a San Francisco based Startup and an online p2p marketplace empowering chefs to easily showcase their brand and host culinary experiences, turning their kitchen into a restaurant. 

The Challenge

The company approached us after they were incubated and seed by Boost VC. They had built an initial MVP product with an outsourcing company in Asia that was very buggy, both on the base code and its visual design. The product were not letting them growth and meet their upcoming business requirements. They wanted to have a more flexible platform and be prepared to support their rapidly-growing community needs. They were looking to partner with an company who could take care of their IT needs.

The Solution

Devsar leveraged its experience on web development and started a huge code refactoring process of the whole platform in record time. The process started with a deep analysis of the underlying platform to identify...

Moni

Challenges: We were contracted to build the first MVP. It took about 3 months of development to have the first system fully working to be presented to angel investors. One of the biggest challenges was to build a real-time smart loan system based on user’s background and financial status. Planned Solution and Innovation: Due to the success of the platform in Argentina, the product will be launched in many other South American countries like Mexico, Brasil and Chile. The team is currently working to enhance and improve the current system architecture to support the expansion of the product. Task: Frontend refactor for mobile API compatibility. Development of new core features (phone credit and invoice payment). Backend refactor for clearer separation of concerns between components. Analysis of use metrics for assistance in business decisions making. Integration with social media (Facebook, Google+).

Blink Webinars

Challenges Client's business goals are to reach a huge global audience with this webinar exclusive video content platform. They needed a scalable and reliable platform that provides ease of use. In addition, they needed an easy to use interfase for final users and clients. They wanted to monetize the content through a membership service. As a small startup, they bootstrapped the entire process with us. Planned Solution and Innovation We built the first MVP, which eventually evolved into a fully functional and scalable platform. The whole architecture rests on Google's infrastructure. We built a video encoder service which reduces the original size of the video without losing quality. Task Custom theme editor which gives the clients the ability to change the look and feel of every webinar. Support for custom domains. Smart mailing lists according multi factor analysis.

Feedback summary: 

Having Devsar as a partner allows greater scalability that’s cost-effective without losing quality. Project management is straightforward, as there’s a point of contact, aside from the developer, to interface with. Throughout the collaboration, their proactiveness and dedication stand out.

BACKGROUND

Please describe your company and your position there.

Hall & Partners is a brand consultancy that helps companies gain a better understanding of their customers and how they engage with their brand. I’m the director of The Hub, our data analytics platform, and am responsible for its health and feature development. I work across all areas of the business, as well as with our clients and our engineers, making sure that The Hub runs smoothly and that we’re creating features that make a measurable impact on our clients' business.

OPPORTUNITY / CHALLENGE

For what projects/services did your company hire Devsar?

We needed a vendor to help us expand our existing development team. Our team was too small for the project’s scope, and we needed a full-stack developer to step in and give us the ability to remain focused on the feature development of our application while still having someone in charge of support and maintenance.

What were your goals for this project?

We manage a multi-faceted platform that we're constantly adding features to. With an aggressive roadmap, we needed to find a skilled resource that could not only join our team but also work independently and still perform. It was important that the developer was experienced in Python, Django, and JavaScript, and could get up to speed quickly on our platform architecture.

SOLUTION

How did you select this vendor?

We researched and interviewed several potential vendors over a period of several months. It was important to us that the vendor was in a time zone compatible with ours, had the ability to scale up if needed, and had the confidence and drive to challenge our thinking. Another consideration was that Devsar is an agency, not a headhunter, so if we scale up, there’s an existing knowledge base within their agency that we can fall back on.

Can you go into detail about the services they provided and the scope of the project?

We have a full-stack developer engaged on an ongoing basis who focuses on feature development. Devsar is responsible for delivering against set requirements provided by me and/or my UX agency. They work closely with our other development team members to ensure that everything meets the goals of our application.

What was the team composition?

Currently, we have one full-stack developer from Devsar. He works with our technical lead/full-stack developer and our frontend developer.

RESULTS & FEEDBACK

Can you share any information that demonstrates the impact that this project has had on your business?

Working with Devsar allows us to scale our development team more economically without sacrificing quality. Having a separate point of contact to deal with allows the assigned developer to remain focused, which has been helpful.

How was project management arranged and how effective was it?

Project management is managed internally utilizing Slack, GitHub, and Zoom for conference calls. We’ve had no issues with coordination, language barriers, or connectivity.

What did you find most impressive about this company?

I appreciate that they have a learning culture and that they’re a part of the broader development community in Argentina. They challenge your thinking, and they have smart people working for them.

Are there any areas where they can improve?

To date, I have no negative or constructive feedback to provide. They’re very proactive, dedicated to the project, and have become an integral part of the team.

Feedback summary: 

Their work was excellent, developing the product on time and within the budget, which ensured it could be shown to key investors. They managed the work effectively, integrating smoothly with the in-house team and bringing their creative flair to the development.

BACKGROUND

Introduce your business and what you do there.

I’m the CTO of Lendealo, a startup that delivers C2C and B2C services in LATAM. We are creating an application that is trying to change the way people consume goods and services, making it more rational and sustainable.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with Devsar?

We were looking for a software development agency to help us build a C2C and B2C online web platform within our limited budget.

SOLUTION

What was the scope of their involvement?

We approached them to create the first MVP of the platform, with a deadline of three months. They build it and delivered the product on time.

We provided the necessary documents describing the functionality and initial scope of the product. They were responsible for designing the layout of the site, creating the wireframes, mockups, and building a fully-functional product.

What is the team composition?

They allocated one full-time, full-stack developer and a part-time project manager.

How did you come to work with Devsar?

A friend of mine strongly recommended them. I checked the company profile, had a couple of calls with them, and then engaged them after a challenge test with one of their developers.

RESULTS & FEEDBACK

What evidence can you share that demonstrates the impact of the engagement?

We had a very inflexible deadline because of a business opportunity with a group of investors coming to town. We launched and were able to make the product presentation on time. It helped us to showcase the product to potential investors.

How did Devsar perform from a project management standpoint?

We used Slack and Google Hangouts as our main communication tools. We chose Trello to manage the project's sprints and track our tasks' status.

What did you find most impressive about them?

They have a really agile, creative, and customer-focused approach. We rapidly engage with them and there was seamless integration between teams.

Are there any areas they could improve?

Not at the moment. I think as we expand our team and add more members, we'll have to find a more efficient way to sync. Right now, we're matching up with what we expected from them.

BACKGROUND

Introduce your business and what you do there.

I’m the director of product for a fitness software company. We’re a startup focused on developing platforms for traditional gyms and fitness clubs that help them reach their members via mobile apps and other digital experiences. The products help users manage memberships and book classes while also pushing content to keep them engaged.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with Devsar?

We had a large contract come in and we needed resources to help build enterprise-grade, robust mobile apps for Android.

SOLUTION

What was the scope of their involvement?

Devsar strictly works on our mobile development for Android. They use Java and some Kotlin for the app, which is native with some hybrid and web view features. Our in-house team created design specs and gave Devsar mockups, which they executed on.

What is the team composition?

We work with three people from their team.

How did you come to work with Devsar?

Our CEO had a contact who referred us to Devsar.

How much have you invested in them?

We’ve spent around $250,000.

What is the status of this engagement?

We started working with them in September 2017, and the work is ongoing.

RESULTS & FEEDBACK

What evidence can you share that demonstrates the impact of the engagement?

The app has launched in the App Store and has between 50,000–100,000 users. It’s had good growth, and the functionality has been well-received. We take feedback seriously and adjust accordingly.

How did Devsar perform from a project management standpoint?

Most of the project management is our responsibility. They’re great at managing their time, checking in, and getting clarity when needed. We mostly use Slack and Google Hangouts for communicating. For task management, we have Asana and Bitbucket.

We broke the work up into two-week sprints with checkpoints and daily check-ins. We have a standardized process, which keeps the communication up and makes it easier for everyone to monitor the progress.

What did you find most impressive about them?

They have great ideas and execute well on all our specs. They’re responsive and knowledgeable, both offering new suggestions but also doing what we ask.

They’re dedicated to our project, which is rare. I’m pleased with their commitment; they’ve exceeded expectations and seem passionate about our product.

Are there any areas they could improve?

No, we’ve been really pleased.

Do you have any advice for potential customers?

Be clear about the scope of what they’re building, the process and timelines, and the bigger picture of the work.

Feedback summary: 

Devsar’s involvement has greatly reduced development costs. They’re efficient at providing frequent updates and their ability to understand projects needs and execute without much guidance is remarkable. They should do more research before adopting a new technology, but overall, the work is great.

BACKGROUND

Introduce your business and what you do there.

I’m the founder and CEO at Educatemia. We have a webinar platform that people use to take free online courses.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with Devsar?

There were no solutions in the market for our volume of users and this is why we came up with the idea of our webinar platform. We needed someone to build it.

SOLUTION

What was the scope of their involvement?

I gave requirements to Devsar and they delivered a phenomenal product that really works — we wouldn’t be able to run our business without it. It’s worth clarifying this that is an internal technology for us and it’s not a live product available for sale in the market. ​​​​​​

There were times in which we had up to 3 developers, but usually had 1 or 2. Our platform was developed in Google App Engine — they used Python, Django, and JavaScript. They also did lots of research on live screening for our webinar platform. The application works really well and we’re grateful that we were able to develop it with Devsar.

How did you come to work with Devsar?

I’ve known Sebastian Serrano, Devsar’s founder, for a long time. He introduced me to his team and we started working with them.

How much have you invested with Devsar?

We have invested more than $200,000 on this platform so far.

What is the status of this engagement?

We’ve been working together for 2 ½ years approximately, and it’s still an ongoing relationship. There’s a functional product in place already, but we still use them for support and adding other features.

RESULTS & FEEDBACK

Could you share any evidence that would demonstrate the productivity, quality of work, or the impact of the engagement?

To be able to accomplish what this technology does, we needed 5 developers in-house and spent $15,000 per month in servers. Now, we only spend a tenth of that thanks to Devsar’s development. I can give them clear guidelines and they are able to understand what we need and turn it into reality. It’s great to have a technological partner like Devsar.

How did Devsar perform from a project management standpoint?

We use Asana and they didn’t have any issues with getting on board this tool. Like any other software development project, they give us weekly or monthly updates depending on the sprint we’re working on. Sometimes deadlines aren’t met, but this is normal. We continue working with them because we believe they are the best option for us.

What did you find most impressive about Devsar?

What impresses me about them is their ability to walk in their client’s shoes, understand the need, and their ability to execute without having to follow through daily or weekly. I travel a lot and this doesn’t affect my project with Devsar. They have the ability to think through the client’s next step.

Are there any areas Devsar could improve?

They are always trying to use the best technologies, which is great, but they could improve on doing more research before jumping into a technology. It has its pros and cons.

Feedback summary: 

The experience with devsar was very good and professional. They kept constant communications and provided visibility into the process which made a big difference for the client. devsar was cited as creative and able to piece everything together.

BACKGROUND

Introduce your business and what you do there.

We provide a dashboard connecting brands, influencers, and content creators through Snapchat and Instagram stories. I am the chief executive officer of the company.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with devsAr?

We needed to build the entire dashboard from mockups and app documentation which we had previously prepared.

SOLUTION

What was the scope of their involvement?

devsar developed our platform using Django Python as a structural basis, with a few other languages mixed in. We had Instagram API, Google Analytics, and Stripe integrations.

devsar assigned 2 full-time developers, as well as some additional resources which helped on small details occasionally.

How did you come to work with devsar?

We wanted to find an offshore partner because of the advantage of foreign conversion rates. We had worked with Indian companies on a previous product, but the communication wasn't particularly crisp, and it was difficult to maintain similar workdays. With a product which needed more attention to detail and an ongoing collaboration, it was important to find a partner in a region that would make sense time wise. We made some research, talked to 10-20 firms in South America, and landed on devsar.

How much have you invested with devsar?

The cost of devsar's services has been between $10,000 and $50,000 for a 2-week project utilizing 2 engineers.

What is the status of this engagement?

We've had a 10-week scope, and devsar delivered on time. We're currently within a 45-day QA period. It has been helpful in cleaning up basic functionalities and language errors. No matter how well the documentation and mockups are prepared, there will still be a period cleanups and changes. devsar has done its best work within this period, even though I thought it would be viewed as a pesky addition to the project.

RESULTS & FEEDBACK

Could you share any evidence that would demonstrate the productivity, quality of work, or the impact of the engagement?

The beta version will only be kicked-off next week, so we don't have feedback from clients or individual users. I've had a very good experience with devsar and found them to be professional.

How did devsar perform from a project management standpoint?

We initially decided to have weekly check-in calls, but they ended up being rarer, mainly because of our side. We kept constant communication with devsar throughout the build, scheduling video calls on Google Hangouts and walking through specific things we had questions for, rather than having devsar simply go ahead and build it.

We switched our communication structure from Slack and email to having QA updates on Trello. The gained visibility into the process made a big difference for us. We are able to make sure that we're staying up on everything and that devsar is accountable. We were also able to login to the platform's admin dashboards and see updates there.

What did you find most impressive about devsar?

devsar has been good at connecting the dots and figuring things out, much more so than the Indian developers we were using. devsar is a bit more creative, able to piece everything together rather than looking at isolated tasks.

I haven't worked with many other offshore firms, but the experience with devsar has been overall positive. They're smart and cordial individuals, with an ability to internalize the objective of the product, thinking critically about particular features and providing better alternatives. That may not seem incredible, but when compared to a developer who is simply going task-to-task while not thinking about how to make a product more successful, it makes a big difference in my opinion.

Are there any areas devsar could improve?

Everything that had the potential for improvement could have been controlled by us better. It was mainly our mistakes that led to poor communication. Making sure that expectations were clear and that we had very good app documentation and design mockups saved us quite a bit of time in the communication department. devsar had a lot to go off of, but we could have done more.

What tips or recommendations could you share that might increase the likelihood of success with devsar?

We needed to clarify if some elements of the project were in or outside of the scope, which happened because we didn't clearly explain the ins and outs of the app documentation in the initial vetting stage. It was our blame, and we've certainly learned from it. My tip is to tidy up the scope, reach crystal-clear expectations, and think about every scenario.

devsAr’s response to the project was great and they were cited as excellent in providing support. They recommended mobile payment features and options that eventually developed interest and attracted users to the solution. The client was overall satisfied with the collaboration.

BACKGROUND

Introduce your business and what you do there.

Parkool is a parking payment startup. We launched our application on December 2nd. 

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with devsAr?

devsAr was in charge of handling the entire project at the programming level. We launched the MVP [minimum viable product] and then they developed an Android platform with the backend and connected an API. ​

SOLUTION

What was the scope of their involvement?

We got in touch since we are both from La Plata, Argentina. We also searched in other places and they were the most interested developers in the project. We figured that they showed real interest in the project aside from the price factor. We made the decision of working with them because they really helped us not only with programming but also in terms of functionality. They were always showing us new possibilities and new development methods. 

How much have you invested with devsAr?

We have invested $30,000.

What is the status of this engagement?

The project has been completed. We agreed on a prototype and MVP that has been finalized. We then maintained connections when it came to the consulting and they’ve always had an excellent response.

RESULTS & FEEDBACK

How did devsAr perform from a project management standpoint?

We don’t have exact metrics to mention because we’re in the evaluation period. What I can say is that they have been excellent when it comes to providing support. One-on-one communication has been direct with the project manager, Martin Riva, and with the Android developer as well.

We were always in contact with weekly sprints and we commented on the proposals. Then, we conducted many, many tests and that was good too. They published APKs [android application packages] weekly so that we could test, and they corrected anything we requested. We are very happy with them and we are even evaluating ways to incorporate them into our company through equity or something similar for future collaborations because their response was great.

They also showed good personal treatment, and aside from the business topics, they were super flexible. I would recommend them 100% and I’m really interested in continuing working with them because we just launched and we will need much more support. 

What did you find most impressive about devsAr?

There’s one specific detail that changed our business model. They presented a solution for adapting ourselves to an actual payment system in La Plata and in many other municipalities that were eventually included to start and complete the parking payments online. We didn’t have that option in our radar until they mentioned it was possible. We developed it, and as a result, it developed lots of interest and attracted users. Thanks to that feature we were able to launch in 30 municipalities. The generated interest to be able to pay for parking through a mobile application was all thanks to them. This situation was developed based on devsAr’s proposal. Another example is that they recommended APKs that we didn’t know about and lots of other things. They were our tech consultants and we found a perfect symbiosis.

Are there any areas devsAr could improve?

In some aspects, they were not as flexible because we had developed most of the project and we figured that we needed a small change. This is not their fault, but ours. We found that there were some issues with the usability level, but that meant reconsidering a big part of the project, so we left it for further changes. This wasn’t a big problem, though.

Devsar has developed this functioning platform up until now since we don’t have our own development team. They handled all aspects and were involved throughout the process related to the development of the native Android application.

SOLUTION

What was the scope of their involvement?

We had 4 developers assigned to the project and we would get additional ones assigned based on our needs. For instance, when we had to dedicate more time to the application, we had a specific developer for the native Android app. The same happened when we needed Python, MySQL, and other resources.

How did you come to work with Devsar?

I'm not sure who referred them but I read that they were renowned in the Python community in Argentina, and that allowed us to move forward with hiring them. We wanted this project to be developed using Python. This is why we chose Devsar.

How much have you invested with Devsar?

Today, we invest $15,000 per month, approximately. It has been more than $300,000 total.

What is the status of this engagement?

It's a continuing project. We had a final product delivered, but we've had sub-products and improvements for it.

RESULTS & FEEDBACK

Could you share any evidence that would demonstrate the productivity, quality of work, or the impact of the engagement?

We are generally happy with the results. They were directly involved with the project. They go above and beyond their developers' role. Informally, they also helped with project management, defining the product when it wasn't well defined yet. Whenever there was an error or any necessary corrections, they were always available to fix those and kept the platform going.

How did Devsar perform from a project management standpoint?

We used Jira and Slack for some things. I think the tools we used were an area for improvement.

They are 100% trustworthy. I believe they are a very loyal team, with good developers, and good coding skills. Our code has been audited and they were open to finding out about errors on their end. Their time management could also be improved.

What did you find most impressive about Devsar?

What I've previously mentioned are their key strengths. For us, it is important to work with a team that we can trust. They created our platform, and today it has 3,000 transactions per month. They deliver good results.

Are there any areas Devsar could improve?

Their project management skills. They need to provide a better outline of schedules, definition of the deliverables, etc.

Feedback summary: 

Devsar’s team was cited as fantastic. The client appreciated their strong Python skills, ability to integrate as part of the team and commitment to doing great work. Devsar also fought for changes they saw as necessary for improving the platform.

BACKGROUND

Introduce your business and what you do there.

We provide a social dating app. I am the director of backend engineering for the company.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with Devsar?

We were a fledgling startup with limited funding and no engineering team. 

SOLUTION

What was the scope of their involvement?

Devsar was leveraged to help us release the first 2 prototypes of our product, while we didn't have a fully-staffed engineering team. The platforms were largely web-based, initially using Google App Engine, Django Python 2, and the Facebook Apps stack. The front-ends were HTML and CSS-based.

The second phase involved building an API for a mobile app. Devsar helped us create it, along with the backend data processing using Heroku Python 2, Flask, MongoDB, Neo4j, Redis, and RQ.

Two full-time developers were assigned to our project. Devsar's co-founder and owner also contributed a significant number of hours.

How did you come to work with Devsar?

Devsar had been working with the company for a year when I joined it. They were discovered by our chief executive officer.

How much have you invested with Devsar?

The cost of our project with Devsar was between $10,000 and $50,000, or slightly above.

What is the status of this engagement?

Devsar started working on our project in the fall of 2011. The project has been completed.

RESULTS & FEEDBACK

Could you share any evidence that would demonstrate the productivity, quality of work, or the impact of the engagement?

I have no hard metrics, but I can say that the people we were working with from Devsar were fantastic. Some of what they wrote was still in production until last month, 4 years later, after having been exercised billions of times.

One of Devsar's members had an anniversary and a visit from his parents at the same time, but he actually left the celebrations in order to perform some unexpected work. That was key to us meeting the date.

How did Devsar perform from a project management standpoint?

We had an extremely aggressive deadline for the second minimum viable product, rebuilding everything from scratch in 2 and a half months. It was a do-or-die launch tied to a $30,000 launch party. We had to have the app done on time, and it had to work well. Devsar's team was fantastic.

What did you find most impressive about Devsar?

Devsar has strong Python skills, being the subject-matter experts in that area for us. Beyond this, Devsar had a commitment to doing great work. I've used a number of different contracting agencies before and after working with them, and I found that Devsar's members made themselves a part of the team, working as if they would be supporting the platform for the next few years. Devsar made a big point out of fighting for the changes they saw as necessary for improving our platform.

Are there any areas Devsar could improve?

No.

BACKGROUND

Introduce your business and what you do there.

Find Your Trainer is an online marketplace which connects consumers with personal trainers. I am the founder and Chief Executive Officer of the company.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with Devsar?

We had built an early prototype/MVP of our solution using some freelance developers. It was time to transition from them, and make the platform more robust and stable. We needed to find a team on which we could rely.

SOLUTION

Please describe the scope of their involvement in greater detail.

Devsar has taken over all of the development responsibilities for our site. The backend of our platform is Django Python. We use Amazon Web Services for hosting, and we use standard HTML and JavaScript on the frontend.

We use 2 and a half fulltime resources from Devsar. They've also assigned us a project manager who oversees the work for 20% of the time. What was most important to me personally, was to have direct contact with the developers, and that they be dedicated to our project, instead of requiring us to find resources out of a huge pool of talent. Our developers are familiar with our technology and code very well.

How did you come to work with Devsar?

We were introduced to Devsar by one of our former freelance developers. I trusted her judgement, so I contacted Devsar, had a few discussions, and went through a walkthrough of what needed to get done on our platform. We decided to pull the trigger without evaluating other options. Devsar was the right fit, principally because they were specialized in our technology.

How much have you invested with Devsar?

The cost of Devsar's services is between $150,000 and $180,000 per year.

What is the status of this engagement?

We started working with Devsar in May 2014.

RESULTS & FEEDBACK

Could you share any evidence that would demonstrate the productivity, quality of work, or the impact of the engagement?

I'm very pleased with Devsar's quality of work. They move quickly, and are very responsive and client-oriented. Whenever there was a mistake, it was quickly fixed. It's been great to work with Devsar.

How did Devsar perform from a project management standpoint?

Our team is a bit wishy-washy in terms of project management. Our requirements, needs, and priorities are constantly changing, so it's rare for us to give Devsar an unaltered 2-week task which has to be finished. We have a continuous process of changing priorities until the work is done.

Because we pay Devsar on an hourly basis, there is no overtime for their team. They work as much as they can during the workday, and leave on time. As such, it's hard to enforce deadlines, and it's not the way in which our relationship is built. I trust Devsar to work as fast and as hard as possible, but they're still working 8 hours per day in the end.

Devsar has an in-house project management tool called Acunote. We use it to manage everything.

What did you find most impressive about Devsar?

I've worked with many offshore developers. Devsar is one of the best we've seen. Having dedicated resources has been our main advantage. Devsar is also only one hour ahead of us in terms of time zones. We can collaborate, talk, and have tests throughout the day. This is a huge advantage over working with a company in Europe or Asia. English is not Devsar's native language, but they have very good skills for the most part.

Are there any areas Devsar could improve?

We used to be rigorous in having a weekly call with Devsar's project lead. We've fallen off of the habit, and only have a call every 2-3 weeks now. This is as much my fault as it is theirs.

What tips or recommendations could you share that might increase the likelihood of success with Devsar?

I'm not a programmer or generally technical, but I've been able to work effectively with Devsar. They're very good at what they do and very client-oriented.

    Devsar is not as cheap on a per-person basis as a developer in Europe or Asia, but we were able to get more done. Devsar has some very good resources.
