Developer for NFT trading with OpenSea API and MetaMask API (Golang)

Need stack developer to write an OpenSea data-scraper using their OpenSea API with a filter system, if a match to the filter is found a transaction is attempted using MetaMask's API and returns the result of purchase. Needs to be written to be easily compatible with a user input json settings value. Ideal languages are: Python (backend), Golang (backend), React JS (front end).

Front end doesn’t have to be anything pretty but modular enough for UI integration to make any changes later.
