Bio
Olena Goncharenko
I had the honour to work with Ihor for almost 3 years, and I can say that I would like to work with him once again. Igor is a person who always tries to find a balance between business and technical needs. It is essential for Igor to build something that others will use and not just feature for a feature or try new technology — highly recommended.

He knew team capacities pretty well, and It is helped to the team did not promise things which team could not do. I can say, that Ihor proactive person who always doing things which he promises. So I can recommend him as a smart and responsible colleague who is eager to help his teammates.
