Konstantin is a great programmer to work with, and if you take the time to communicate with him clearly the specific goals and have realistic expectations of what you want, then you will get great results. He asks good questions and has good insight into how to approach various technical and non-technical issues which is an important quality to have and although I do not know him personally, I think he probably is an interesting human being as well.
