    Senior Mobile Developer
Senior iOS/Android Apps and Games Developer

I am mobile apps and games developer (for iOS and Android) with more than 7 years of experience. I'm very serious about code quality and flexibility. So it's always easy to support long-term projects, develop and integrate new functionality.

I have been developing for iOS since 2011. During this time I gained experience in the development of small and large projects, as well as their support in the AppStore. The number of such projects includes several clients for social networking, client application for video surveillance systems, client apps for customers electronic payment system WebMoney and others.

Also I have experience in 2D-games development based on Cocos2D-X engine (C++). In the developed games were used skeletal animations for the characters, shaders for implementation of special effects, surround sound, etc.
