Trading with defi Api metamask

I am looking for a freelancer to assist with trading with a DeFi API in Metamask. I would like help setting up the Metamask API, as I do not currently have that in place. I will require assistance with the setup as I do not know how to do it myself. My specific interest is in DeFi trading, although I am open to looking into crypto-currency trading, derivatives trading, and other related options as well. If you have expertise in this field, please get in touch and I'd be happy to discuss further.

Specifically, my interest is to buy Coin or Token in the pre-launch,This practice will be done manually, but then at the time of the listing my interest is to give an exchange target in BNB.
