Ivan's one of a kind. From the moment we heard about his story during the interview process we were amazed by his sheer will, interest and indefatigability.

During the time I worked with him I was privileged enough to work with him on some features. Ivan is the type of professional that does not cut any corners, is always eager to learn more, explore new ideas, collaborate and help others in a heartbeat.

It's a personal objective of mine to be able to work with Ivan once again. Top professional and an amazing person.

The best programmer who ever worked at my company. Agile and persistent in resolving errors, tenacious in programming (as one should be) and temperamental (we're human). He seemed like a rubber man; the more I asked, the more he did (and did well). He programmed in Android but also works very well in Objective-C. Late but well-deserved recognition.
