iPhone Developer

“Oleg is a very capable iOS developer with deep understanding of the platform. He also was very instrumental in adopting my generic app design to iPhone (which asked for creativity). One thing I found very frustrating though was the amount of bugs, and consequently the amount of testing on my part required. I have to qualify this however: this particular app was rather complex.
