Boris is what I would call a software craftsman. He posseses extensive knowledge not only in specific field I was working with him on, but also in a multitude of other technologies. He comes up with elegant solutions for any problem he encounters and does it in a fast and efficient way. However, something even more important to me, that I'd like to emphasize, is his marvelous attitude in regard to the work he performs. For him, the are no compromises in functionality or quality of the code. His responsiveness and deep sense of responsibility are remarkable as well. Boris met all our expectations and delivered high-class, quality product, and now continues to provide excellent post-deployment service. I trully enjoyed working with Boris on this project and I'll be happy to cooperate with him in future as well.
