Great programmer. He finished the task within a week, just as he promised. After handing the product over for testing, he fixed every issue and added the extra features we came up with during the test period. I definitely recommend him!

He built a full CRM system for Telegram, and I am happy with the work. There was a $150 prepayment, the rest was paid on completion. He did the job very fast and sent progress updates every day. Any changes or requests were handled very quickly. Recommended.
