Bitcoin Forum

I am looking for expert Solidity Developer who can use current git repositories of existing defi project to create a new one with making some edits

Did you mean someone who can forking the existing code that has already used by most of defi? that's quite difficult to find someone who will able to do that. Visit this site and i hope you can meet what you are looking for https://forum.ethereum.org/ I guess that will be related to the smartcontract.

You paying in bitcoin? might post this as well on Services.

Maybe someone who can do this is hanging out on freelancing platforms for bitcoin just like in sub-reddits.

Also try to surf topics here, you can find ppl who are looking the same staff https://bitcointalk.org/index.php?board=12.0
I was looking 5-10 minutes and still have no results, sorry

The project development section is a section that has already created dedicated to the bitcoin development and you will find nothing there. You must visit the ethereum forum to get the people who have an expert in the development of the solidity program.

You will be also feeling so damn hard to find that in the altcoin section too as there was no section that already dedicated to the altcoin development.
Mostly solidity developers active in the ethereum forum.
