He's the best:) Always professional...Always on time [05 October, 2016] Have turned to him many times now, and every time he has been a clear communicator who is quick to respond and produces what I need...No matter what the job is, I offer it to him before making it public first. [24 August, 2017] Never lets me down! [18 March, 2018] Made quick work of it as always!...He is highly skilled with Excel.

Actually knows what he is doing, how to do it, and when to do it by. The ability to follow instructions, complete tasks, and prosper, are all some of the key traits Grigori has. He has made me happy with his brilliancy.
