I am looking for a professional over 5 years experience Blockchain developer

We are developing a project and our backend developer can't continue working because he has no experience with Blockchain.

He has implemented some API endpoints for user management, admin panel, etc.

So you will work based on the current backend and implement the remaining API endpoints for deposit, wallet, trade, etc.

Our backend is developed using Node.js Express and MySQL database.

Your task is to develop smart contracts and develop backend api endpoints to integrate with the smart contracts.

This is what we have built until now. please work on this

1. Please setup our project environment and database server with the sql file in the db folder.

2. And develop the "Test" token smart contract and deploy it to the testnet.

3. please create a test api endpoint "getbalance" that receive Ethereum wallet address from the request and get the Test token balance of the address and respond it. And then test it using Postman.

You make a short video of the full test process to show that you can handle the project successfully.

And then send me video.

If you are available please bid for our project.

Node.js MySQL JavaScript Smart Contracts Solidity
