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.

Ideal skills and experience:

- Experience in developing and implementing smart contracts on blockchain platforms

- Proficiency in programming languages such as Solidity, Node.js, or JavaScript

- Strong understanding of blockchain technology and its principles

- Knowledge of different blockchain platforms and their capabilities

- Ability to customize and tailor the blockchain solution to meet specific requirements

- Familiarity with security protocols and encryption techniques used in blockchain systems

Node.js JavaScript MySQL Solidity
