It's very simple. I don't recommend it, he kept reminding me all day to pay him for his work, I made the mistake of releasing payments to him step by step and after he saw the entire amount in the account he doubled the value of the project ,then when I encountered some problems with the payments . tells me .. he has to pay two other developers who helped him, in the end I didn't receive anything from the money I gave him $3k because f.com took part of the money and he didn't chose nothing.
