Serghei C.

I am satisfied with Sergey’s work. He is attentive when studying the technical specifications, very prompt, and takes all requests into account. We are still far from launching the system, but as far as I was able to test, everything looks great and works well. There are some minor details regarding the logic of the calculator that need to be fixed, but due to subjective and objective factors, we agreed to correct them later, step by step. A competent and responsible performer, I recommend him to everyone!
