ABOUT ME

iOS/Xamarin/.NET expert

I am passionate about Computer Science and Mathematics Software Engineer. Skills of architecting and building complex user-oriented systems and applications are in my blood. In combination with business needs, I can turn any idea into understandable requirements for the team and finally, build it the most effective way, plus keep the quality on the highest possible level.

In spare time, I am heading up to the perfection in every aspect of my life, by improving physical form, increasing reading speed, building better сhess skills, leveling up overall endurance, and doing many other interesting or maybe stupid things. Being said, it is the long way to go, so far I'm somewhere in the middle.
