I worked with him for the first time, but he immediately realized what I wanted to get in the result!
Communication went extremely fast, the answer was received immediately, without expectations!
The deadlines for the work were clearly determined and Sergey invested in them with a large amount of time.
The cost of execution is more than fair.
I took into account absolutely all my mistakes and corrections in the process of work.
If one phrase characterizes Sergey then he is a professional who quality and mainly works quickly on the result, without excessive disputes, takes into account the interests of the customer, if necessary goes to a compromise.
