Сотрудничество не получилось ввиду проблем с нашей стороны, но на этапе переговоров фрилансер показал себя с хорошей стороны - и контактность и профессионализм побудили выбрать именно его среди почти 30-и других предложений.

The project was not completed until the end, as a force was created. The major circumstances are both from my part and from the executive. I can't say about the skill of the execution because it doesn't rush to work.

All assigned tasks have been made errors have been corrected as possible. The man had to fix the "cats" of the previous master, and everything that depends on him he performed!
He can explain properly and clearly. The eye works quickly. Always in contact, which is not very important! I explained a lot in the work of the store already on my own initiative, for this huge + !The price was also pleased!
Soon we will contact again!

Very quality all done and in the specified time, affordable price and confident knowledge.
It is most likely that everything depends on the technical task. If it is complete, then there are no nuances. Maybe in the future we’ll be looking for such services again, so I’ll recommend it to others.

Thank you Sergey!
He did what was required, and on my fault there were some problems due to the failure that he had to fix.
There is no claim to the quality of the work performed, he did everything in time, while he was constantly in contact.
I recommend Sergey as a professional!
thank you.
