Good communication, he knows his job.
The task was difficult to explain with words, only a person who understands and knows the task could do it as required. When choosing an executive I spent on the correspondence with other freelancers over time and half explaining how and what to do and what can be done. But with Sergey it wasn’t so, he just wrote one proposal that he understood everything – he’ll do everything. I first doubted because there were no reviews and a new registration was. As a result, I'm very happy that Sergey did everything in the best way, without any extra questions - even more than it was at first in TZ. And with the price I was lucky because the work he did is more expensive! In one word, I am happy, I recommend all Sergei, you will not regret him master of his business.
