Sobre mim
I build Web3 dApps and MERN stack applications using Solidity, React, Node.js, Express and MongoDB. My work includes smart contracts, wallet connections, REST APIs, database integration, authentication and backend development. I have hands-on experience with NFT marketplace contracts and web application backends. From a small React feature to a scoped MVP, I focus on clear requirements, functional testing, readable source code and practical setup notes. Message me with your project goals so we can agree on the right scope and delivery plan.... Saiba mais
