UI/UX Design Review from Wladimir Wolinski

Communication was smooth either through our teams communication channel or with the project manager via email. We were in daily contact with the UX/UI designer in form of dailies or when we had to clarify some questions. With the project manager, we had a short conversation every 2 weeks to clarify all possible questions. We personally love to work in a very process-oriented way. Because when we understand how to do something, we usually know how the end result can look like. With Digis, we also had the feeling that they knew what they were doing and how to do it. Every next step was planned from the beginning. If something didn't work in line with our processes, we could readjust it. We were basically satisfied with everything.

Both the developer and tester have exceeded expectations. Their performance is excellent. Together they eliminated bugs, introduced new features, and ensured that the app is working without problems.

Software Development Review from Dominique Dujardin

The product was developed successfully and has been undergoing pilot usage. Hexagon IT Solutions managed the engagement effectively, delegating tasks and assignments between us and the team. They met timelines and communicated efficiently through Slack. Their resources also resolved bugs quickly. Hexagon makes it easy for people trying to develop software. Ultimately, Hexagon was and has been on the same page with us from the beginning. They knew exactly what we were looking for, and what we didn't want. Other software development firms jumped at us with marketing proposals, designers, and irrelevant business consulting. Hexagon IT Solutions took the time to understand who we are and offer us their services accordingly.

Plavno was creating profiles with pulling up a lot of information (clusters). Xunit-based scoring was used when setting up a .NET 2.0 project. Scoring for this format works similarly to Junit.

This development can change cluster parameters, cluster management system (current state of the object), customize vectors that lead to this cluster and make predictions.

Staff Augmentation Review from Sergey Novik

Were developing an internal image processing tool for our design team and needed two machine learning engineers, since our core developers were busy with other client projects. We required extra hands familiar with Python and computer vision, so after a developers market review, we hired them from SumatoSoft. The SumatoSoft developers joined our team and were able to swiftly adapt to our workflows, which resulted in them delivering the working models well before our hard deadline. Communication was straightforward throughout the engagement. We had video calls and exchanged brief text updates on a weekly basis. The delivered code is clean, and pull requests are well-documented. I appreciate that they pushed back on a few of our initial architecture ideas. They challenged our original approach and proposed a better method for handling the model weights. We plan to bring them back for the next phase of development.

Web Development Review from James Leonard Ehrlich, DVM

I wanted to outsource front end development while maintaining back end services myself. They started with existing React SPAs, cleaned them up, found and removed bugs, improved user interaction, made clear requests for new endpoints which I implemented and they tested and used. The time difference between my office in eastern USA and theirs in Moravia worked well, as we could meet at their afternoon/my morning and I had the rest of the day to deal with back end or questions they might have. Their professionalism and competency were impressive. I will continue working with them, for years, I hope, in maintenance mode or when we need to expand features.
