************This is my major!****************************
As a senior blockchain developer, I have 3+ years of experience in blockchain projects. in especially, hyperledger network.
The skills that you required are so many.
Maybe nobody can be familiar with all skills.
I think you also want to look for a developer who has rich experience not all experience.
I have experience in Solidity, Rust, Web3 frontend integration(React + Web3), Uniswap, ETH, BSC, Polygon, NFT marketplace, ICO, Staking,
