The first and main trait of Konstantine is his technical erudition: he read a tons of books thus knows a lot of inforamation, patterns, methods and approaches. In this way he always know several correct and short solutions. This is a very important skill for any profitable IT company. The second and equally important trait is his way of colleagues communication: he finds and hires specialists with good and positive behavior of communication thus his technical circul contains not only good technical specialists, but also people with a comfortable way of communicating. Working with Konstantin you always can have a informal talk to find the best solution for any issue. In my book it is because of he has dramatically huge experience of software development. He has enough experience of big teams management. Now he is developing himself as a great manager and I hope he will do as well as he can. If you have technical challenges of your development department you have to grab a opportunity to hire him.
