A Clutch analyst personally interviewed this client over the phone. Below is an edited transcript.

BACKGROUND

Introduce your business and what you do there.

I’m a product owner at Yieldbird, a company that helps publishers increase revenue. We mostly focus on programmatic advertising.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with CODEST?

We work with hundreds of publishers and wanted to provide them with a tool to better track and analyze their revenue. We needed a partner to develop the product.

SOLUTION

What was the scope of their involvement?

CODEST has been working on our project from conception, collaborating with our internal team to improve ideas and outline the product’s features. They conducted market research and helped build a proof of concept and minimum viable product (MVP). They’ve worked in a plethora of technologies, including Ruby on Rails, JavaScript, and BigQuery.

The product helps publishers dive deep into their revenue data and provides analytics that enables them to make smarter business decisions. It was built in the React framework and connects to the Google Ad Manager API, which many of our clients use. We’re currently doing live testing to receive feedback on the tool.

What is the team composition?

We work with a team of seven people. The scrum master is our main point of contact, but I also have direct access to the other team members.

How did you come to work with CODEST?

They were a recommendation.

What is the status of this engagement?

We partnered in June 2018, and the work is ongoing.

RESULTS & FEEDBACK

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

Because of them, our business is much more transparent and scalable now. We no longer need to do manual reporting—the tool makes nearly the entire process automated, which saves us time and money. The product is a more advanced way of analyzing data and provides better insights in a more visual way.

How did CODEST perform from a project management standpoint?

We follow an agile methodology, but CODEST is flexible and willing to adapt to our needs. We can present new ideas, and they gladly implement them. Communication is easy and straightforward, and we mainly use Slack, video conferences, and in-person meetings.

What did you find most impressive about them?

They’re well experienced and proactively provide suggestions to make the best product possible. They push back if they think something could be better, which we appreciate.

Are there any areas they could improve?

Everyone can improve, but I’m not sure what CODEST could do differently.

Do you have any advice for future clients of theirs?

Be open and share your ideas with them. They’ll work with you to improve them, so share as much as possible.

BACKGROUND

Introduce your business and what you do there.

I’m the engineering manager of an e-commerce company, operating online stores in Lithuania, Latvia, Estonia. We provide thousands of people with construction, household, electronics, interior, garden, and leisure goods to help them make their house into a home. Established in 2015, we were announced to be the best e-shop by the technology and innovation festival LOGIN in 2016.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with CODEST?

Thanks to our well-organized daily workflow and having an effective model of cooperation, we were able to build a new payment provider, data anonymization tool and multi-language functionality for our online stores.

SOLUTION

What was the scope of their involvement?

CODEST’s developers are engaged in the development of our products using Ruby, Rails, MySQL, PostgreSQL and Docker technologies. We wanted a partner with the same technology stack that we’re using in our team.

In the first stage of our cooperation, they were responsible for creating a tool for data anonymization. Then, they integrated the Worldline payment provider into our platform.

In the next stage, CODEST worked at the multi-language functionality which allows our clients to surf the shop in the Russian language. Nowadays, CODEST’s developers are working on an integrated app/shop with Inbank payment provider.

What is the team composition?

We started with one developer to see how well we work together. Then another developer has joined the team to fulfill our growing needs. Currently, we work with three CODEST developers on a full-time basis.

How did you come to work with CODEST?

We lacked good candidates here in Lithuania and decided to search abroad. CODEST used the same technology stack as us and their hourly rates were good. We decided to give them a trial project, an MVP, which worked really well. On top of that, we organized some new features and improvements. In general, this project converted from a locked contract into a full-time position. We saw the quality within the first three weeks.

What is the status of this engagement?

We started working together in January 2019 and the work is ongoing.

RESULTS & FEEDBACK

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

I’m really happy with what they deliver on a daily basis. We are happy with the quality of their development efforts and their hourly rates. 

How did CODEST perform from a project management standpoint?

We have a project management tool where we have a backlog. It helps us to keep track of what’s going on. We also use Slack for quicker communication as well as daily standups.

What did you find most impressive about them?

They deliver what they promise and meet deadlines. They’re really good at estimations. There’s a balance between the quality and the rate. They give us good suggestions and feedback from their experience. It’s a good collaboration.

Are there any areas they could improve?

Can’t come up with something right now.

Feedback summary: 

The collaboration with CODEST produced the affiliate network, and despite later issues with its stability and performance, it enabled the company to run its essential operations for several years. The team was always a great partner and now has more experience in the field.

A Clutch analyst personally interviewed this client over the phone. Below is an edited transcript.

BACKGROUND

Introduce your business and what you do there.

I was the e-commerce director for a large Polish publisher running multiple press titles and websites. My department was responsible for running an online affiliate network.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with CODEST?

We needed them to write a web app from scratch, which would serve as the heart of our affiliate network, fulfilling all the needs connected to it.

The most important functionality was a tracking service—the app would collect information about every single click and lead generated by the network and count all the money. There would also be functionalities for building statistics, sorting, assigning traffic to the network publishers, and running financial operations.

SOLUTION

What was the scope of their involvement?

They developed the web app using Ruby on Rails, with PostgreSQL and MongoDB databases. It ran on quite complicated infrastructures requiring a number of database instances. The team wrote it from scratch and were also responsible for a large part of its administrative functions and quick improvements to assure the stability of the system.

What is the team composition?

I worked with Jakub (COO, CODEST), but the developers were usually our main points of contact. They were replaced from time to time, so there were a number of people working for us. Tomasz (Expert Ruby Developer and Dev Manager, CODEST) worked with us for the longest time, along with one other team member.

How did you come to work with CODEST?

I was mandated to work with them, as CODEST is part of the Agora group.

How much have you invested with them?

At the time of my departure, the rough combined cost was around 1 million Polish zloty, or perhaps a bit more (approximately $267,000 USD).

What is the status of this engagement?

I worked CODEST from 2014–2018.

RESULTS & FEEDBACK

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

This collaboration was essential—the affiliate network couldn’t have come into existence without CODEST’s work. The application served as the very heart of our business. It covered all essential operations for publishers running ad campaigns, financials, and so on.

I’m partly satisfied with their work. In the very beginning, the application ran well: it was stable, and it provided all the functionalities we needed. However, as time passed, it became a little messy, and some bad practices accumulated. During the last year of work, we had a number of problems connected with performance, stability, and optimization, which cost us a lot of time, money, and led to some stressful moments. These problems appeared after three years of continuous development on the app, including data consistency and code optimization.

How did CODEST perform from a project management standpoint?

We worked with them remotely on a daily basis. There were a lot of email and phone exchanges, and the developers acted as a remote part of our team. We also had longer remote conferences 2–3 times per week.

I was satisfied with the level of collaboration as they were always at our disposal, they answered emails and phones instantly, they had good engagement, and they addressed problems in a professional manner.

Often, they fulfilled duties that were meant for infrastructure administrators, rather than developers. There were some glitches with our hosting company, and CODEST was a great partner for us in solving these problems.

What did you find most impressive about them?

As a business manager, I’ve only worked with Agora’s internal IT team and with CODEST. Compared to my former IT department, I appreciated the quality of CODEST’s service. They’re faster, better programmers, more engaged in projects, more responsive, and so on.

Are there any areas they could improve?

They could’ve produced better-quality code. They made some mistakes designing the database structure, which became ineffective after a few years of continuous use. The quality of the code they produced wasn’t top-class, but I can’t say they’re incompetent, either. They made the application from scratch and their level of understanding into our needs and requirements was high.

This was the very first affiliate networks application that CODEST produced. It’s possible that some flows in this app were inadequate because of their lack of practice in the industry. Our own team was also new to the requirements, so we were less accurate when forming our requirements.

They could also improve by planning more before working on the design, especially around databases. This would make them more flexible and expandable. A microservices approach would make their apps less bloated and more manageable.

Do you have any advice for future clients of theirs?

Commit CODEST to produce the app. They have more experience now, and application development is in their DNA. Clients should hire developers that are not only good, but who have experience; who know the structure and requirements of a field, and who know the directions in which an application can develop. This will aid in avoiding some young-age mistakes that can then bias the ongoing development of the product.

Secondly, work closely with the team to design the core structure of an app and its database. Leaving it solely to the developers can backfire later on when the market pushes the company to steer the app in a new, unexpected direction.

Finally, let CODEST take care of server administration and configuration. Committing a third party to run the infrastructure is a bad option, as gaps emerge in the communication between the developers and the admins. CODEST is capable of running an infrastructure, so I advise picking a cloud hosting solution and bringing CODEST in to deal with it in a top-down manner.

Feedback summary: 

The final version launched in 2017 and CODEST continues providing updates and bug fixes when requested. Since completion, the business has been able to monetize the archive. CODEST works efficiently and responsively. Customers can expect a team that delivers quality results in a timely manner.

A Clutch analyst personally interviewed this client over the phone. Below is an edited transcript.

BACKGROUND

Introduce your business and what you do there.

I’m the IT director for the newspaper segment of Agora SA. My responsibility is to help businesses build new business models and products based on subscriptions, specifically web and mobile apps.

Our IT department's split into two business divisions: general IT services for the whole company and development teams for essential business units, like business transformation. Together, the department develops and brings products to the market.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with CODEST?

We were trying to transform our traditional newspaper model into digital form and focus on selling subscriptions, not just newspapers.

SOLUTION

What was the scope of their involvement?

CODEST created a digital product based on our archived, printed newspapers. The digital archive has specific features aimed at helping customers find information, including a full-text search. The content is delivered through a backend and partial fronted, for display.

Their team used Ruby on Rails technology for the platform. It’s based on an API structure that delivers data from our archive. The index is based on an Apache Solr solution on the backend. Files are imported from the file system and exported to a MongoDB database.

They delivered a partial HTML design of the website, while my team provided some elements. CODEST also worked on the UX/UI based on our definitions, checking the accuracy for the people working in the backend of the materials we publish. We worked together as two teams.

How did you come to work with CODEST?

CODEST is part of the same group as our company. It was a given to go to them when looking for available resources.

What is the status of this engagement?

We started working with CODEST in March 2017, and the product was sent to the market in October of that year. The final version launched in December 2017.

RESULTS & FEEDBACK

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

After the final platform was implemented, we continued to make changes and bug fixes. Just recently, we asked CODEST for extensions. We spend an average of 20–25 hours per month on the work.

The general mission of the project was to build a channel for delivering news to subscribers. Once it finished, we were able to monetize our archive, which wasn’t available to us previously.

How did CODEST perform from a project management standpoint?

We worked with their team using the agile methodology, splitting the project into two-week sprints. At the end of the sprints, their delivery time was excellent and what we expected from them.

What did you find most impressive about them?

CODEST provides a professional service. Their approach to product delivery worked great for our team. Any issues we identified, they quickly fixed. Overall, the results were quality for us.

Are there any areas they could improve?

When a new developer was introduced to our team, we had to explain the project information and rules. CODEST didn’t provide everything, but other than that, the rest of the collaboration went smoothly.

Do you have any advice for future clients of theirs?

It’s important to define the rules of the collaboration and roles of each team member from the start. If everything is transparent in the beginning, it’ll help productivity.
