Hi, Richard As a senior full stack and blockchain developer, I have rich experience with dApp development such as smart contact, NFT marketplace projects and something like that using the multi chains such as ethereun, cosmos, binance, and so on. In my career, I built a lot of NFT marketplaces such as auction and fixed method using react, web3, etherjs, solidity, hardhat, truffle, and so on. For the projects, I built the smart contract using erc20, erc721, erc1155 and deployed it to the ethereum, cosmos, binance chains and so on. And integrated the NFT contract with the front end using react and web3. So I can implement your project successfully very shortly. If you are interested in my skills and experience, I am available to chat with you anytime. Regards.
