    Great all around. He got the job done, and apparently knew everything he needed about the technology. I did not have to babysit him at all. He promptly implemented the touch up changes I wanted in the final product. He seemed friendly.

    Extremely resourceful person and he delivered this project in perfect working order on time. He added suggestions to my original spec for a web crawler data extraction project which were extremely useful and added greatly to the job. Great Work !

    Mr Chapyuk was a fantastic programmer to employ. He maintained excellent and fast communication throughout the project, whilst displaying his technical skill to a great level. The project was completed way ahead of schedule. I would most certainly hire Mr Chapyuk again. Thank you.
