I worked with Andrey for the first time - he is a very good specialist, demonstrating himself as a strong and responsible developer within a complex fintech project with high demands on architecture and security.

Andrey quickly immersed himself in the business logic of the project, proposed adequate technical solutions, and consistently maintained the quality of the code at a good level. I recommend him as a reliable backend/fullstack developer for complex web platforms and fintech products.

I was satisfied with the collaboration with Andriy, even despite the technical issues from the Apple services and other events from personal life that unfortunately occurred and greatly affected the project completion time, but were not dependent on us. In the future, I plan to reach out again with new projects and updates on the already completed work.
