In the Murka company, I was in the development of a slot project from scratch. I fully made
many slots by TDD with the art team. Later I mastered Unity3D + C# development and
continued as Unity3D developer with the salary of a Senior developer. There I created some
features, fixed some bugs in core architecture, and made many slots.

In the GAF Media company, I was a deputy team leader. Some versions of the GAF Converter
were released under my direction. The most stable ones.

Before that when I worked in iLogos, I was the lead of the Flash team. We worked on the
Slotolotto project. It’s a slot machine game combined with a lottery.

I enjoy the time when I am responsible for the work of the team. I perform my best when I
delegate all my work to competent team members. I used to check the code operability of all
teammates and figured out corner cases. Also, I used to find out how to fix some errors and
solve technical issues.
