Personal 90 USD

I do not recommend this freelancer. Deadlines are stretched to the impossible – instead of the agreed time, the work has not been completed even after a long period. He constantly promised that the project was almost ready, asked for 1-2 days for review, but did nothing. He responds to messages selectively, creating the impression that he is just stalling.
A waste of time and trust.
If you value your time – look for another performer!
