Feedback summary: 

The platform offers cutting-edge capabilities without sacrificing user-friendliness or accessibility. Stepwise plans meticulously, implements best practices, and delivers outstanding results. Their lean methodology is the ideal environment to foster creativity and innovation. 

BACKGROUND

Please describe your company and your position there.

I'm the CEO of Self Learning Solutions, which offers advanced tools to support business processes, decision recommendations, and scoring in the fintech sector. Our solutions are based on machine learning, deep learning and AI.

OPPORTUNITY / CHALLENGE

For what projects/services did your company hire Stepwise?

We hired Stepwise to build our platform. They chose the technology, designed the architecture, and developed its tools. We were also looking for a long-term partner to help us evolve our business and build new tools.

What were your goals for this project?

We needed a cloud native company with strong technical skills that could collaborate smoothly with business and data science teams. We also wanted a partner oriented toward machine learning and AI, with the capacity to work with algorithms and neural networks.

SOLUTION

How did you select this vendor?

A colleague with a technical background recommended Stepwise’s architect. After exchanging ideas about how the platform should look, we decided to hire them. Our teams had the same vision for the technology's business functions.

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

Stepwise ran workshops with us to clearly understand our goal, our target users, and our processes. Then their architect did the research and chose the right technology. They used Google Cloud Platform, Flowable, Java, TensorFlow, and Python. They have also supported us as we talked with Google representatives to obtain credits for our MVP on Google Cloud Platform.

After they designed the architecture and had it verified by our business and data science teams, they began development. It’s ongoing, but the MVP was ready for customer tests after only two months. That was impressive.

What was the team composition?

Stepwise supports us with a cloud and solution architect, a senior developer, and a data scientist support manager. Their CEO facilitates our communication, project setup, and business development.

RESULTS & FEEDBACK

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

The MVP is a decision engine for business process management. Thanks to this platform, we can offer a revolutionary product to support loan and credit businesses. It can be a decision and scoring engine, a platform for maching learning implementation, or a model for deep learning and AI. Business processes and rules can be developed with n-dimension decision tables. It's useful for manual or automatic credit decision processes. Most importantly, the construction and development of its processes can be completed by analysts, not just IT staff.

How was project management arranged and how effective was it?

They take a professional, experienced, and client-oriented approach. They tried to understand our needs before starting development, which has definitely avoided problems and eliminated unnecessary costs.

They implement a high-level development process with best practices I've only read about before. They set up communication tools and ticketing systems and propose one-week sprints for maximum flexibility. We closely monitor progress and plan our next steps together.

What did you find most impressive about this company?

Two aspects of our cooperation are the most impressive. The first is their technical knowledge and the quality of work they deliver. The second is their approach to software development. They do the right things in the right order, and their lean approach is perfect for launching innovative ideas.

Are there any areas where they can improve?

Their prices are high for the Polish market. However, their experience, quality, and professionalism justify everything. It's hard to find anything negative.

Feedback summary: 

The audit produced a bevy of advice regarding future microservices opportunities. Stepwise left a convincing first impression with their professional attitude and ability to acclimate themselves to an existing project. Their experience and quality make them strong contenders for future work.

BACKGROUND

Please describe your company and your position there.

I am a Head of Development at Empik Group. Empik.com is one of the biggest e-commerce businesses in Central-Eastern Europe. Our portal offers over two million products and has over two million active users.

OPPORTUNITY / CHALLENGE

For what projects/services did your company hire Stepwise?

We needed someone to perform an audit on our microservices-based, backend architecture. In addition to that, we needed the resource to perform a container-based virtualization.

What were your goals for this project?

We wanted to bring on an architect with experience in the microservices architecture area to bring our existing backend architecture to a new level of quality and performance, through an audit. Moreover, we wanted to solicit potential recommendations for a future update of our architecture roadmap.

SOLUTION

How did you select this vendor?

They were recommended to us by one of our internal employees. After initial talks and relevant know-how verification, we decided that the services Stepwise was offering met our requirements perfectly.

Describe the project in detail.

The architect did a deep, initial analysis of our existing backend architecture, after which, they proposed implementing microservices with Spring Boot to cooperate with our existing architecture. They also helped set up a continuous delivery environment for microservices using Docker, a virtualization program, Jenkins, an open-source Java automation server, and a code versioning strategy that was appropriate for our architecture.

In addition to the audit, the architect performed the following development tasks: container-based virtualization, cloud server configuration, server- and client-side support for externalized configuration in a distributed system, an archetype project for building up microservices, abstraction over rest-based calls, circuit breaker failure detection, and functionality degrading when a method calls fail.

What was the team composition?

We worked with a single architect that Stepwise provided.

RESULTS & FEEDBACK

Can you share any outcomes from the project that demonstrate progress or success?

Thanks to the audit, we now know how to build microservices that are compliant with our existing architecture. The approach they proposed facilitates our current monolithic architecture rebuilding. When we’re starting to work on a microservice, it’s now much easier to get a grasp of what it’s doing and how to combine it with our systems. The audit also produced extremely important recommendations for our future, which our team is currently analyzing, taking into account various pathways to integrate the proposed options into our internal roadmap.

How effective was the workflow between your team and theirs?

It was a professional collaboration from the very beginning. The resource managed to enter a project that was already running and handle tight deadlines. The initial knowledge transfer was very smooth, and the architect cooperated with our internal team. The audit itself was not an isolated piece of work, but rather a collaborative, day-to-day process involving various team members.

What did you find most impressive about this company?

The stand out is their experience level and quality of audit work they delivered to us. In addition to that, the recommendations they left our team are excellent and will definitely help us in the future. We are, of course, considering cooperate with the Stepwise team again, if the right moment comes along.

Are there any areas for improvement?

We found their pricing quite high as Polish market standards. However, their experience and their level of commitment is definitely worth it.

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

Stepwise did an initial, in-depth analysis of the existing backend, which helped us make an educated decision on which technologies to utilize. Their scope around backend development started with mainly bug fixing, but evolved into more feature development to improve our product.

Feedback summary: 

The custom solution is currently in use and is functioning very well, with no issues at present. The intense collaboration involved 10 days of daily reviews throughout which they maintained good attention to detail. The team is flexible and worked hard to understand the company’s work. 

BACKGROUND

Introduce your business and what you do there.

Lecko is a small company based in Paris. We work in digital information and teach companies how to use new collaboration tools. I lead the development team. 

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with Stepwise?

We were trying to retrieve data from an enterprise social network called Yammer. The idea was to build a reliable web solution.

SOLUTION

What was the scope of their involvement?

They took the existing software and analyzed the code to see where we can improve processes and other areas. When they finished that analysis, they told us what needed to be modified and did those modifications. They then wrote other code, which is better now than it was previously. It’s a native Java Hub running on a server.

What is the team dynamic?

There are 3 people on the team.

How did you come to work with Stepwise?

They sent us an email about their services. After a short interview, we decided to give them a small task to test their capabilities. It was very good and so we gave them this project.

How much have you invested with them?

5,000 euros [$5,930].

What is the status of this engagement?

We started working together in August 2017 and the work is ongoing.

RESULTS & FEEDBACK

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

It's very functional. We’re currently using the solution in our production environment and it’s perfect. There’s nothing to improve. It’s a small part of a bigger project, but it’s working very well.

How did Stepwise perform from a project management standpoint?

It was a significant collaboration. We spent around 10 days making reviews every day to be sure we were going in a good direction. The project management was very light and was good because it was easy. We used Google Hangouts and Slack to communicate.

What did you find most impressive about them?

They are adaptable. We are the only ones doing what we’re doing, and so they have had to understand our job and how we work.

Their price is also good. They’re from Poland which means they are very cheap compared to French developers. That’s a very good aspect to them.

Are there any areas they could improve?

Sometimes we had trouble communicating because we use English and neither of our English is perfect. It was nothing that prevented us from working together. It’s not just something for them to improve because my English has to be improved too.

Feedback summary: 

Stepwise managed the project efficiently and expedited the product launch in time for a major event. The team recommended features that led to a robust platform. The collaboration was successful, thanks to Stepwise’s technical expertise, clear communication, and competitive pricing.

BACKGROUND

Introduce your business and what you do there.  

I am the product manager and owner of ClearHub, which is a product of Clearvision. Clearvision is one of the largest Atlassian partners, delivering services and licensing support for all Atlassian products and tool sets. Clearvision is the trading company that we are operating under.

ClearHub works directly with a client, offering a full-service team when required. We're not a recruitment agency, but we do pick up freelancers who are available for contractual work. Our company has an existing process of finding people or getting experts that we have worked with in the past. We concentrate on projects around the globe that last for 3, 6, 9, 12 or even more months.

ClearHub is using the technical expertise of the Clearvision Professional Services. Clearvision’s credible and vast knowledge of Atlassian tools, allows ClearHub to support and upskill their contractors.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with Stepwise?

We needed a platform for marketing, and we also wanted to automate our services. The end goal was to create a platform similar to others out there in the market, like Upwork and Guru.com. We wanted to get as many Atlassian contractors as we could under the umbrella of ClearHub. The platform would help us deliver our services by upscaling them and training people.

There were a lot of challenges with product development. We wanted to create the simplest possible option. We had to work around some issues, such as the need to define the right programming language. One of our U.S. software architects helped us identify the best tool to use.

SOLUTION

What was the scope of their involvement?

Stepwise shared their knowledge and expertise. We already had a proof of concept on Ruby on Rails, but they identified that we wanted a more robust solution for the future. They were not Ruby on Rails experts, so we discussed using Groovy on Grails, which is a Java-based language. While I wanted to avoid using a Java language, Grails itself is based on Java so it was inevitable. Fortunately, it was a great solution. The timelines and roadmap we put together ticked all the boxes we wanted at that point.

We wanted to integrate other parts of the website, specifically Salesforce and Pardot. Connecting with Google Analytics is the simplest option, but our schedule and budget didn’t allow for it. We are still thinking of doing that for the second version of the existing MVP [minimum viable product] platform.

What is the team dynamic?

The key members from Stepwise were Radek and Rafal, who were software engineers. Kamil was the QA tester. Krzysztof, the Scrum master, assisted us as well. Internally, we also worked with Andrew, a software engineer from Clearvision. He had a PHP background, so Stepwise trained him on this specific language. They allowed Andrew to gain experience and knowledge around Grails, and it was a great opportunity to see how Stepwise operated.

How did you come to work with Stepwise?

We learned about Stepwise through one of our colleagues in the Clearvision office. As a business development person, he came across Stepwise through some work we were doing with clients in the territory.

We discussed if they could assist in creating a new web platform for ClearHub itself. We appreciated their technical skills, and their rates were also completely different from what we were looking at in the U.K. and the U.S.

What is the status of this engagement?

It was a three-month contract, from February to May 2017. The platform is live right now, and we completed it ahead of schedule. We're now using Stepwise as an outsourcing house in Poland.

RESULTS & FEEDBACK

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

One of my biggest requirements was to create a robust application, and that's what they've delivered. I can confirm that we’ve never had issues. Until now, the website operates perfectly. I also requested that they deliver the product early so that we could use it in one of the largest events for Atlassian. Stepwise successfully delivered the product half a month ahead of schedule.

In the software development industry, it's never a good idea to go to production on a Friday, especially before a bank holiday weekend. Our relationship with Stepwise gave us the confidence to go to production on a Friday, sure that nothing would break over the weekend. Radic and Raphael are high-level software engineers, so we were crazy enough to do that before returning to the office the following Tuesday.

The most exciting thing part was that we got our first client six hours after the new website was launched. We still don't know how that person found ClearHub and how they landed on the website, but they went through the process, signed up, and requested a contractor. We were surprised about how nicely it all went through.

How did Stepwise perform from a project management standpoint?

We were in constant communication, so we knew that we were going to deliver on time. Time is money in the software development world. I don't want to waste anyone's time, and I don't want people to waste my time as well.

We communicated through Slack using three channels: a channel for next steps, a channel for development, and a channel for day-to-day details discussions as a team. We had sprint demos every Friday as well as weekly meetings. Occasionally, we also had important ad hoc conversations. As the product owner, I talked with them about next steps and defined stories, to see if we were going to move ahead with those.

What did you find most impressive about them?

From the beginning, we were impressed by how well they communicated as well as the transparent and direct relationship that we had. They were very helpful and open. It's always amazing when you put people from different backgrounds and languages together. We had great teamwork, and we were aligned professionally.

Stepwise delivered an end result that was better than what we wanted. The final product included stronger features that we didn't have in the initial scope. They also delivered earlier and with smarter features than we expected. We will definitely work with them again in the near future.

Are there any areas they could improve?

They're a startup company, so they don't have a huge capacity or an extreme amount of resources. They definitely need to expand their development team and have some more junior people. It's just a matter of clarifying their vision for their company and what they want to achieve in the near future.
