Erwin, during the execution, quickly and professionally dealt with the tasks placed, taking into account the wishes as much as possible. I was constantly in contact, which is not very important!

Видел видео на yuotube.com смотрится достойно.

Посылка пока не пришла, так что авансом, по уровню общения и готовности фрилансера ожидаю, что все будет как и раньше на достойном уровне.
Поэтому оплачиваю ( не получив пока на руки результат работы, т.к. не имею возможности забрать лично).
Качество работы подниму до 10 получив изделие на руки.

The work is done at a high professional level.
The executive showed high professional skills not only in programming, but also in assembly, installation and installation technology. It is easy to understand the requirements of the customer's process.
Due to the fact that the “Iron” was processed on the way, he actively participated in the making of design decisions. There was no delay in the deadlines.
I recommend ! Although, usually such performers are not recommended to a wide range, but they adhere to themselves and their own. If necessary, I will call again.
