Certified expert (ACE) in Flex 4.x (since 2012).

Currently I'm an independent developer, freelancer, consultant and a teacher. And a lead of indie game-dev group in the past two years.


I teach children and adults to program. Also I’ve been a co-initiator & speaker in the RAFPUG.

As a hobby sometimes I work on some features for couple of interesting oss-projects.


Just for fun & knowledge reversing favorite cool old games (before 2000) and making remakes - crossplatform rebirth. Mostly for private usage.

First of all, in the past developers put their hearts to the old games and treated them as an object of art. In these games there is always a story, humor, they are fun, interesting and surprising and honest with the player, unlike most modern profit-centered games. Such games must teach our children!

Secondly, the old games inside is a storehouse of information. Earlier there were not so much computational resources and people worked more carefully with memory and graphics. The reversing of the old games teaches a lot and this is madly interesting!
