Full Stack Developer Mid Level

I’m a full stack developer working mainly with Node.js, PostgreSQL, TypeScript, and React. I’ve contributed in early-stage environments, helping evolve legacy systems and build internal tools that simplify data access and everyday workflows. My focus is on building practical, maintainable systems that improve how teams interact with data. I’m also increasingly interested in the Ethereum ecosystem and looking to start building in Web3, particularly around smart contracts and decentralized applications.
