•	Developed server-side expression engine for lazy evaluation across linked forms to guarantee updating of stale values and at the same time maintaining UI usability and responsiveness.

        I’ve known Alex quite long, since 2011, I suppose. Alex is a good team player and it was very comfortable for the whole team to work with him. He started as mid developer and then grew to senior software developer and was involved mainly in doing important and challenging tasks. He was also responsible for team unit's work. 
I could say that Alex is very responsible, attentive to details and result-oriented person and of course, I would be glad to work again with him if there were such an opportunity. There were quite a lot stressful situations in a project and Alex managed to stay calm and find solutions for the problems, which inspired a lot the whole team.
