BACKGROUND

Introduce your business and what you do there.

I'm the product manager at Beautiful Company, a startup e-learning system.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with 7ninjas?

We engaged 7ninjas for web design services for our product.

7ninjas created designs for our web-based platform, using tools such as InVision to create the UI/UX for 8–10 different web pages.

What is the team composition? 

We worked with a designer and product manager.

How did you come to work with 7ninjas?

We found them on Dribbble and ultimately liked their portfolio and how they reacted to our project. They were also very responsive, friendly, and supportive from the start.

RESULTS & FEEDBACK

How did 7ninjas perform from a project management standpoint?

They're very reactive and organized. They did a good job of pricing out the scope of work without being overly rigid about charging for every minor detail. If other members of their team joined a call, for example, they didn't charge us extra for their time.

Their whole process was very advanced; they used the latest design tools and delivered high-quality work that was easy to pass along to developers.

Feedback summary: 

7ninjas delivered a functioning web app, and they’re currently addressing any bugs in preparation for its launch. The team is highly collaborative, communicative, and smart. Their dedicated team boasts a variety of skills; each member works quickly and diligently to produce results.

BACKGROUND

Introduce your business and what you do there.

I’m the co-founder of a company that provides a roommate matching software for colleges, universities, and apartment complexes focused on student housing.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with 7ninjas?

We were in the process of transitioning our website from an outdated legacy software built with PHP technologies to a new platform. We wanted an updated frontend experience that leveraged our backend API endpoints. The app needed to be faster and more accessible. We looked for a vendor to help us with developing the new web app.

SOLUTION

What was the scope of their involvement?

7ninjas developed the entire UX for web app across laptops, PCs, iPads, and other tablets. We provided designs, and the team built them out using React. The app helps users find roommates through networks, specific matching groups, and compatibility scores. Users can either like or skip over potential candidates based on lifestyle, college majors, and housing preferences. 7ninjas integrates an external API to allow chatting on a digital discussion board. We’ve also implemented an account management process and notification system as well.

What is the team composition?

I mainly spoke with our project manager, but I occasionally interacted with the lead developer and a QA specialist.

How did you come to work with 7ninjas?

I found them through Clutch.

What is the status of this engagement?

We started working together in August 2018, and the project is ongoing.

RESULTS & FEEDBACK

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

My technical team praises the app, and they enjoy working with the 7ninjas team. They’ve been highly collaborative. We feel comfortable launching the current project, but we’re still working through some bugs. We’ll probably be done by the end of October.

How did 7ninjas perform from a project management standpoint?

Their project management system is good. We have a daily call through Google Hangouts, but we also use Slack and Trello. They’re very responsive and knowledgeable, working efficiently through each task. We’ve never run into scheduling issues—their timing is on point. 7ninjas is also very good about communicating their needs, making sure we provide the necessary information and updates.

What did you find most impressive about them?

Working with their project manager has been great. He’s communicative and responsive. We wanted a high-quality, cost-effective solution. He’s doing his best to meet our needs, really looking at the product form the client’s point of view. The developers are also great. With a quick turnaround time, they deliver working prototypes that reflect different elements of the app.

Are there any areas they could improve?

No, there aren’t. The only hiccups we’ve had were related to billing, converting USD payments to Polish currency. We don’t do wire transfers that often, so it was a little confusing, but we’ve resolved that.

Feedback summary: 

Open and direct communication was key in fostering a collaborative environment throughout the project. The 7ninjas team listened to new ideas and provided substantive feedback to find the most effective solutions.

BACKGROUND

Introduce your business and what you do there.

I’m the owner and co-founder of an internet telephony service provider (ITSP) that works with various companies across Europe.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with 7ninjas?

We needed a web portal that would allow clients to manage the services we provide to them, including a dashboard that compiles a detailed overview of key metrics like calls received, call distribution across different countries, and so on. We tried to build the system internally, but didn’t have the resources needed to complete the job. We reached out to 7ninjas to supplement our team.

SOLUTION

What was the scope of their involvement?

7ninjas helped us build all components of the system, including both design and frontend/backend development. The backend integrates data from different services, including an internal database, and external data pulling via APIs. We had the option to code with Python or node.js, and we adopted the latter.

The primary goal of the project was to build an MVP. We’re currently testing the product with our first customers and are making improvements based on the feedback we receive.

What is the team composition?

The size of the team varied throughout the project. At minimum, we worked with one backend and one frontend developer, a business analyst, and a project manager.

How did you come to work with 7ninjas?

A friend of mine told me about their team and the work they do. They came highly recommended.

What is the status of this engagement?

We worked with 7ninjas between November 2017 and March 2018 and are currently collecting customer feedback on the current product.

RESULTS & FEEDBACK

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

We need to improve constantly, which is why it’s very important to listen to feedback from customers. We are working with new and returning users.

How did 7ninjas perform from a project management standpoint?

I really appreciate their team’s direct and open communication, especially with their project manager and business analyst. This has given us a different perspective on the project. Our approach to working with 7ninjas has given us the opportunity to explore new ideas and find the most effective solutions possible.

We used different tools to communicate, including email, Slack, and Skype. I have also travelled to Poland in order to have face-to-face meetings with the team.

What did you find most impressive about them?

Communication was key to this project. The whole 7ninjas team was collaborative and easy to work with. We could share and consider different points of view in creating the platform. Their technical skills were also very impressive.

Do you have any advice for future clients of theirs?

I advise customers to reach out to the 7ninjas team and have a preliminary discussion. Brainstorm as many different possibilities for the project as possible and work with them to find the best options.

Feedback summary: 

The new site 7ninjas boosted user engagement significantly. Their cost-effective work, high-quality deliverables, responsiveness, and reliability helped foster a successful, continuing relationship.

BACKGROUND

Introduce your business and what you do there.

I am the CEO of Founders of Color, an online community for minority entrepreneurs dedicated to helping grow and sell their businesses.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with 7ninjas?

We wanted a new website that didn’t use WordPress.

SOLUTION

What was the scope of their involvement?

I was very pleased with the logo design work they’d done for us previously, so when I found out they did web development as well, I hired them for to build our new site.

They built us a custom site, doing all of the design and development work in Python and React.

They now provide maintenance and updates on an as-needed, retainer basis.

What is the team composition?

I interacted with about six people at the firm, including designers, project managers, and both co-founders. There are also other developers on the backend, but I didn’t interact with them directly.

How did you come to work with 7ninjas?

I was considering other firms, but I was most concerned about aesthetic and was impressed by the quality of their work. A lot of developers use stock imagery for their job examples, but it was really important to see that they had done something similar to what I was looking for. I found a site that they had developed that I was really impressed by. They gave me some pricing, which I compared to other developers and found it to be really competitive.

How much have you invested with them?

I've invested $20,000.

What is the status of this engagement?

We started working with them in January 2017, and the site launched that August.

RESULTS & FEEDBACK

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

People love the beautiful site they built. It's gone a long way toward establishing our brand. As we secure further resources, I plan to update the site quarterly since it’s been a major driver in building our community. Currently, we have about 2,700 subscribers, and I attribute that success solely to this great site.

How did 7ninjas perform from a project management standpoint?

They are incredibly responsive. They only bill me once a quarter because I don't give them enough work for them to bill me monthly. Whenever I reach out, however, the team is always very communicative and gets it done.

When we were building out the site, we had a couple Skype calls and used Slack and Trello, but since then we’ve used email exclusively.

What did you find most impressive about them?

I love working with them and have no desire to go anywhere else. They’re trustworthy, affordable, and have always been incredibly fair. I can also tell they value me as a customer and I wish I could afford to do more with them. I wish them all the success in the world!

Are there any areas they could improve?

When you are dealing with people with no development experience, it's important to set expectations. While something like adding a button might seem very simple and straightforward to me, it can be incredibly complicated from a development standpoint. It’s not just 7ninjas that could do a better job educating its clients, but all developers. Many clients only have experience using WordPress, which has a strong user interface, and transitioning to a custom site requires completely different knowledge. They could have done a better job explaining what it would take to run the site. I'd find it helpful if they developed some product, quick tutorials, or videos to help their clients be better clients.

Feedback summary: 

7ninjas' multifaceted development acumen is evident throughout the project. The team's technical expertise, flexibility, and receptivity to feedback are key assets. They lead projects efficiently and communicate effectively. Consequently, the engagement continues to grow.

BACKGROUND

Introduce your business and what you do there.

I'm the managing director and lead designer for a mobile application development shop based in New Zealand.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with 7ninjas?

We were looking for extra resources to help us with an app because the contractors we usually work with were busy. It was a tight time frame so trying to keep the search just within our local community wasn’t going to work. We decided to look for resources overseas.

SOLUTION

What was the scope of their involvement?

We generally build B2B apps but this particular project is a consumer-driven app. The app’s purpose is to help people stop smoking through a cessation program that uses vaping to replace combustible smoke from cigarettes and helps with nicotine withdrawal. There’s a timed-release video program and notifications that alert the end user that a new session is available. The app also includes a chat function for peer to peer support. Users can discover others in their local area to talk about the general struggles of quitting an addiction.

We gave 7ninjas the bones of the app (UI design, UX design, and a set of technical specifications) and how we wanted it to function (wireframe, navigation, and a clickable prototype) and they’re building it based on that blueprint. In addition to leveraging cloud services from Firebase and Google, they’re taking a cross-platform development approach and using React Native to fit within budget and the initial build timeframe. The app will be available for both iOS and Android.

What is the team composition?

I’m in contact with about five members of their team. Because I'm a developer myself, I can work directly with their lead mobile developer.

How did you come to work with 7ninjas?

We put an ad on Upwork and interviewed some firms but the results were a bit hit or miss. We eventually had a few good conversations with 7ninjas and decided to give them a shot.

What is the status of this engagement?

We started working together in late October 2017 and it's an ongoing relationship.

RESULTS & FEEDBACK

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

We’re really happy with their work and the support they're providing through the development process. The app is very close to launch. At the end of this week, we'll finish the completion document but we're still planning new modules. We've had a few errors that were created on our side and they've been really great in helping to remedy those.

Their involvement has been strictly development to date but we’re planning to use their design team in the future. We’d also like them to provide support for the app post-launch, so we're working through that process as well.  

How did 7ninjas perform from a project management standpoint?

The project management and account management teams are great. The project manager has been very helpful in making sure the process stays on track and steering everyone in the right direction.

They're quite open and transparent. We have access to their development boards so we can see where tasks are instead of waiting to hear an update. The communication with their development team is strong through Slack, even though there’s a 12 hour time difference between New Zealand and Poland. I'll catch them at the beginning of the morning and they catch me late at night and it’s great to be able to talk and have those quick catch ups each day.

What did you find most impressive about them?

I’ve worked with other outsourced development teams and they generally won't offer an opinion. It's quite refreshing to work with a team who’s willing to say “That’s good but this might be better.” It's a very collaborative relationship. We don't consider them outsourced developers for hire but rather see them as valuable members of the team.

Are there any areas they could improve?

I think there’s always small technical changes that need to be made but they've been really open to feedback and fixing any issues.

Feedback summary: 

The websites were well-received due to 7ninjas’ superior development abilities and their use of the most advanced technology available for an optimized user experience. Throughout the projects, they remain self-sufficient and communicative.

BACKGROUND

Introduce your business and what you do there.

I’m the founder and owner of a digital creative agency that handles website development, digital campaigns, etc.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with 7ninjas?

I needed a skilled front-end coder to assist me in developing my clients’ websites.

SOLUTION

What was the scope of their involvement?

They worked with us on several projects, but most recently, they developed the front-end of one of our hotel websites. We provided them with a rough blueprint of what we’d like the front-end to look like, and they developed it using a variety of software, including HTML, JavaScript, and SAS.

What is the team composition? 

We primarily worked with a project manager, two developers, and Eugene Malinin [Co-founder and CFO, 7ninjas].

How did you come to work with 7ninjas?

I searched UpWork for a front-end developer and found Eugene, who was a freelance developer at the time. After partnering on a project with him, I decided to continue working with him. He eventually co-founded 7ninjas and recruited a larger team. I remained Eugene’s client throughout the building of his company.

How much have you invested with them?

I’ve invested between $5000 to $6000.

What is the status of this engagement?

I began partnering with Eugene in December 2015, and we finished our latest project in April 2017. Because 7ninjas has expanded its clientele, they’ve became more expensive, but I’m inclined to continue working with them because they produce high-quality work.

RESULTS & FEEDBACK

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

Every project they’ve worked on for me was very well-received by my clients. As a result, those clients have continued to partner with me.

How did 7ninjas perform from a project management standpoint?

They did a good job. I have no complaints. I don’t have to look over their shoulder constantly. I give them a brief of what I want, they work on that, they bring what they have back to me, I give them my feedback, and we cycle through that process until the work is completed. We use Slack to communicate and Trello to leave feedback on ongoing work. 

What did you find most impressive about them?

Unlike other freelancers I’ve found on UpWork, Eugene is extremely forward-thinking and has a firm grasp on high-quality development. He uses the latest technologies to ensure the best user experience. 7ninjas is the most impressive front-end development firm I’ve worked with.

Are there any areas they could improve?

I prefer to work with a developer directly as opposed to a project manager because I’d like to communicate with a small team to ensure nothing gets lost in translation. 7ninjas has expanded since I started working with them, so I’ve had to work with their larger team. But I recognize this as more of a preference on my part, as opposed to something negative about them.

Do you have any advice for potential customers?

I would advise that potential customers, regardless of the firm, have a clear idea of what they want. Don’t be vague about your expectations.

7ninjas complements the regular team, and possesses a strong breadth of knowledge. They excel at all aspects of the process, and accommodate distance-related issues.

BACKGROUND

Introduce your business and what you do there.

I am a co-founder for a software consultancy that builds products for large businesses.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with 7ninjas?

We’re US-based, and like to hire good overseas partners to supplement our talent for various projects. We had a large project that needed three extra developers.

SOLUTION

What was the scope of their involvement?

They participated in the build, attended our daily standups, and helped us conceptualize the project. We worked dually on app and web development through React Native, which allows users to create iOS and Android apps from one codebase. We built one framework for the website, and a second one for the apps. 7ninjas helped with both frameworks for the various platforms.

What is the team dynamic?

We hired three developers from their team. Most of our communication was via Slack.

How did you come to work with 7ninjas?

My business partner discovered them through a Google search.

How much have you invested with them?

We spent around $50,000–$60,000 this year.

What is the status of this engagement?

We started working in April or May 2017. The original project has ended, but we’ll continue partnering with them in the future.

RESULTS & FEEDBACK

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

We’re very happy with the work they’ve done for us.

How did 7ninjas perform from a project management standpoint?

We handle project management, and their developers integrate into our team. Interfacing with their developers and their non-technical staff went well and ran smoothly.

What did you find most impressive about them?

They’re good at every aspect of running a consultancy. They follow up with clients, and resolve any issues with billing. They’ve provided solid developers with a good breadth of knowledge.

Are there any areas they could improve?

They did very well overall, but we didn’t always have 100% of their focus.

Advice for potential customers?

There are inherent challenges collaborating with an overseas team. 7ninjas takes time difference and communication into consideration, and are accommodating partners.

Feedback summary: 

Though their coding skillset and industry knowledge are of the highest quality, project management and scheduling proved challenging at first. After taking the feedback to improve themselves, they are now part of a long-term, ongoing relationship.

BACKGROUND

Introduce your business and what you do there.

Our company is based in Bratislava, Slovakia, and we develop social e-commerce websites. I'm the CEO.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with 7ninjas?

We were looking for people good in their craft and suitable for our needs.

SOLUTION

What was the scope of their involvement?

They're developing both the backend and frontend of our web app. It is custom code based on React framework, and the backend is Node.js. The React ecosystem is a big feature, and many technologies have been used there.

What is the team dynamic?

We've worked with 7 to 8 members of their team, with around 5 people currently working on the project.

How did you come to work with them?

We tested many subcontractors. 7ninjas was very good in the execution of the first task I gave to them.

How much have you invested in them?

We have spent around €100,000 [$118,000 USD].

What is the status of this engagement?

We started working with them in August 2016, and the work is still ongoing. We will be launching the app later this year.

RESULTS & FEEDBACK

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

We've had iterated versions while we've been working with them. After each part, we test it and provide feedback, which they then incorporate into the product. Although it's sometimes a little stressful, feedback is positive overall, and their team handles it well and better than other subcontractors.

How did 7ninjas perform from a project management standpoint?

Initially, the project was not managed very well. I provided feedback, and they changed things in the way they ran their company, so management has gotten better. We are 85% satisfied.

We communicate mostly through Slack and internet channels. We've also met a couple of times, and it's never a problem to call them on Skype whenever I need to discuss something.

What did you find most impressive about them?

They know what technology is trending currently, and they focus all assets on it. They work with trending technologies like React and Node.js. I am a programmer myself, in the same industry, so I can tell if everything's going well. I have been happy with them because they're good listeners, and they are able to develop what I want.

Are there any areas they could improve?

In project management, things could sometimes be communicated more clearly.

Feedback summary: 

Both app versions, improved by high-quality code and innovative features, have launched to positive user feedback and high ratings. 7ninja's enthusiastic and collaborative team with around-the-clock availability continues to impress.

BACKGROUND

Introduce your business and what you do there.

SportyHQ is a membership and competition management platform. We help sporting organizations run competitions, like tournaments and leagues. We also do run rankings, court bookings at clubs, class event management, etc. I’m the president of the company.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with 7ninjas?

We already had an iOS mobile app to score squash matches. A previous company had built the Android version, but it was poor quality. We wanted 7ninjas to rebuild the app in React Native because that lets you make an app one time and have it work on iOS or Android.

SOLUTION

What was the scope of their involvement?

They rebuilt the iOS app to be cross-platform compatible, which included building the Android app.

The app lets users score a squash match on a basic level. Users can set up the scoring system, add the players, general parameters, and points, and track any disputes. The app also ties into our service: if we have a client running a tournament on our platform, users can live score the match. While inputting points, they get sent to our server in real time and can follow along online. At the end of the match, everything gets updated. 7ninjas also helped us with live scoring for leagues, a feature they added.

What is the team dynamic?

They’re a great team, and everyone speaks English really well, which was important for us. They’re all young, enthusiastic, and engaged in their projects.

I worked with one or two people from their team when we were building the app. They are now redesigning our website, and the relationship is quite collaborative; I seem to meet a new person every day. They have a business developer whom I spoke to originally about the website. I’ve recently been dealing with the product manager, and today, I spoke to a designer. They’re all willing to get on the phone and help with any issue.

How did you come to work with 7ninjas?

We were using an independent contractor for our website, and I talked to him about our app. He suggested we use React Native to get what we wanted, and recommended us to 7ninjas.

How much have you invested with them?

We’ve spent more than $20,000.

What is the status of this engagement?

We started working together in May 2016, and the relationship is ongoing.

RESULTS & FEEDBACK

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

We are extremely happy overall. The app is on both stores and has close to a five-star rating. I play squash myself, and I see people using it all the time. The feedback we’ve received has been quite good, and from my own experience, the app is reliable and doesn’t crash.

Even though I’m a programmer, I didn’t know about React Native when I hired 7ninjas. I’ve learned it since, and I can see that their code is high quality.

How did 7ninjas perform from a project management standpoint?

Their communication is good, given that most of it happens online and they’re based halfway around the world. I can also talk with anyone on the team in their Slack channel. We mostly chat during Polish business hours, but if I need something early or late, they’re always accommodating. They’re a very open and accessible team.

What did you find most impressive about them?

The quality of their work and their communication makes them stand out. Their team cares and is fun and enthusiastic. I went offshore to save money compared to the US, and I’m sticking with them for all these reasons.

Are there any areas they could improve?

The only issue we’ve had is payment. I send wire transfers to them, which is not the most convenient, but it’s not a massive negative.

The Review
Feedback summary: 

The platform boasted impressive conversion rates significantly above the industry average, mainly due to its accessible layout. 7ninjas distinguished themselves with their smooth project management and comprehensive view of the project's goals. They always made user experience a priority. 

BACKGROUND

Introduce your business and what you do there.

I am one of the co-founders and the CFO of Flymble, a next-generation travel platform powered by fintech. We allow users to spread the cost of their flight tickets over monthly terms so that they can fly now and pay later. If someone wants to travel and the cost of a ticket is $500, with us, it can be spread over monthly terms, so travelers pay $50 per month.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with 7ninjas?

We started the company because we wanted to travel to Bangkok, but we didn’t have the money. We worked at a bar for three months, put aside the money, and had to pay $200 extra because the flight cost had increased. With Flymble, people can get their tickets right away, months in advance. We built the first version of the website on our own, after learning how to code. Eventually, we couldn’t handle the work anymore.

SOLUTION

What was the scope of their involvement?

They started with a structured process about the customer needs we wanted to address. We then integrated the design ideas we had in mind with 7ninjas’ process. They created a design, and, from there, developed the whole work. We don’t believe in mobile apps for this purpose since people only want those for day-to-day things. However, 7ninjas did make the website mobile-responsive.

We needed to rebuild the entire booking website. We sell tickets on a payments basis, but, before this step, we needed a search engine. It involved quite a lot of work with the APIs of other booking partners. 7ninjas integrated spread payments partners and connected complex systems like fintech loan generators with a booking platform, which are very complex things.

Everything was built from the ground up. For the frontend, we used React.js together with Redux, which is the technology used for Facebook. They also used JavaScript ES2015+, webpack, Babel, Yarn, ESLint, stylelint, Flow, RxJS, Reselect, Immutable, Lodash, Ramda, PostCSS, SCSS, CSS Modules, and Foundation for Emails 2.

On the backend, we used Django and Python-based languages. Our work involved the Django REST Framework, Django Channels, Tornado, Celery, and Haystack. The other technologies used were PostgreSQL, Redis, RabbitMQ, Ansible, Vagrant, Docker, Terraform, Amazon Web Services, Apiary, and Swagger.

What is the team dynamic?

The team size varied depending on the work needing to be done. On average, we had 5–6 members from 7ninjas. At the peak of the project, we had 12 people. There was also a period during which we focused more on sales and less on the product. That meant there were 2–3 months with no work.

How did you come to work with 7ninjas?

We approached multiple development teams via Upwork and met with them. We even traveled all the way to Warsaw to meet 7ninjas. Immediately, we could see that they were much more focused. They could see the bigger perspective—where we wanted to go and the best way to achieve that. In contrast, other agencies asked about our needs and immediately offered to execute them without thinking.

How much have you invested with them?

I don’t know the exact figure. So far, the total cost has been €150,000–€175,000 [$177,202–$210,000].

What is the status of this engagement?

Our first contact with 7ninjas was in June 2016, and we started working together in the first week of July. The first version of the booking platform was done in record time, launching in 6–7 months. We’ve just released the first version of the website, and the work is ongoing.

RESULTS & FEEDBACK

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

We’ve just released a new version of the platform. The previous one had massive conversion rates, of around 1.5%, whereas the travel industry averages 1.1%. Based on feedback, we needed to make the process more explanatory by educating the users. We’ve done just that with the new version, where we’ve added a “How it works” on top and a tutorial. Our first vision was to make the website playful and friendly, but the feedback we got drove us to change our style.

How did 7ninjas perform from a project management standpoint?

The project managers are concerned with identifying the fundamental customer pain points. They’re communicative. We mainly use Slack and phones for communication. We’ve also visited 7ninjas frequently.

What did you find most impressive about them?

Project management is one of their strongest points, especially in the case of our contact, who joined the company two months ago.

Are there any areas they could improve?

It would be great to have a public platform for tracking invoices. They send out invoices every two weeks, but we need to manage our cash flow, and we sometimes ask for more work.

Do you have any advice for future clients of theirs?

They take the process broadly, which could irritate some people looking for companies to do what they want to get done. It depends on what the client is looking for. In our case, it is great that 7ninjas provided a fundamental look at our project. It can be a long process, but it has worked out well for us.
