    Konstantin is truly amazing at his craft. During the interview phase he stood out from the rest of the applicants with extremely detailed questions about the project, ensuring that there was no confusion once the project started. He turned around what I thought to be a complex project within a few hours. The end result after only one revision was perfect. If you hire Konstantin you better mean business. He really knows his stuff and asks very specific questions. This is a good thing that only leads to successful projects. I can't wait to find more work for Konstantin so I can make use of his services in the future.

    s_konstantin is a very experienced javascript expert. He helped us out on a complex front-end issue with a lot of dependencies. The way he writes his front-end code is very professional, structured and clean. He had to manage our task will very little information, so he had to analyse the existing (complex) business logic. From that analysis he wrote a flow document and upon confirmation he wrote the code. On delivery we missed on important item which he managed to fix within a day. We are recommending s_konstantin for any complex work you have.

    After I researched in detail the problem, I realized that there is no "right" solution in this situation if use the conditions that have been set. That is what I explained to the customer in my proposal. The answer I received was: " I believe you're correct. Submit a bid for a couple of hours of your time..." In summary: I trust that the customer
