Great work by Valentyn. He took his time to understand the idea of the website and was asking questions to make sure it was made the right way, thank you.

ERC20 token, Uniswap V3, Add entry to map variable inside transfer function without sending the tokens.
I had to explain him several times what the issue is and he was still not able to understand it. Every time he would come back to me with a new contract telling me that the issue was solved but it wasn't. He did released the escrow payment after I told him I can't waste more time explaining so I appreciated that. I wouldn't hire him for complex solidity jobs, not because he is not a good developer (I wasn't able to find if he is) but because he wasn't able to understand the project needs.
