Sergey P.

Top-Rated iOS/Android Developer


Kharkiv, Ukraine


I've been developing for iOS platform since the first public SDK release back in 2008. I bought my first Android device the same year and immediately started developing mobile applications for both platforms. Over these years I gained lots of experience, tried almost every single SDK feature and became a real mobile development expert. Now I'm one of the top Upwork developers with more than 30,000 worked hours and 4.9 customers review rating. Please check out my portfolio and don't hesitate to contact me.
