It was easy to discuss any nuances, as Oleg quickly enters the essence, speaks only on the case, finds simple solutions to complex tasks, always on communication. As a result, the parser was even better than I expected when I created the project. 10 out of 10 in all points. Cooperation is very pleased. A lot of thanks.
