If you need a project done and done right, Kostia is the guy to use. He communicates clearly and works hard every step of the way from dev to qa to interating on the build. He has a solid and easy to follow work flow that makes it a joy to work with him. The app he built for me does exactly what I need it to do and I couldn't be more thrilled. If you're able to communicate what you need you app to do, Kostia will deliver and that delivery will be top notch.

Understood what was asked of him perfectly and worked on it diligently, couldn't have asked for a better person to work with.
