    “This project was meant as a test to see if this kind of collaboration would make sense and I must admit that I am susprised by the level of professionalism that Sergey has shown. If he's willing, I will surely be hiring him again in the future for my big project. I wasn't really happy with the first implementation, which wasn't sufficiently specified/designed by me and he has proposed a better solution to me and implemented it the same day.”
