Frontend for NFT staking game + smart contracts

We are building an NFT-based staking game on the Ethereum blockchain. We need a solidity developer who has proven experience building reward systems. We have the NFTs live already, with a staking contract.

We need a front end that enables users to interact with various contracts (more details will be provided). We require gas efficient and otherwise optimized smart contracts.

We are hopeful this project will allow us to get additional funding for greater functionality build-out and subsequent projects. The quality of your work will directly impact this.

Need Experience with:
・Metamask wallet integrations
・Dapps
・Staking mechanics
・Raffle
・Frontend (React / Java )
