A great person, an excellent specialist, knows everything in his own business and a little bit in the affairs of everyone else. All the visual design of the media of my projects I boldly trust him, because even without the presence of the right input he is able to guess everything and “sweat the cushion from the top” in the end.
Generally, you can write for a long time, just work with it and don't hurt it;)
Good luck to everyone! And Sergey patience and the right customers!
