I have created several ERC20 tokens (simple to make) but have integrated a couple into similar react/nodejs/dynamo, react/nodejs/postgres, systems. I personally write the smart contracts and I have a couple other guys help me with front end dev and web3 development to ensure we meet best practices and generate proper code structure etc. One project isn't live the other is a backend and I'm not able to share as it is an admin panel for the backend of a game. Do you have a design for UI/UX? Do you have an auditor for the smart contract? Do you have all the functionality figured out for the smart contract?
