About me
I'm a MERN stack developer who spends most of my time on the front end — turning complex requirements into clear, accessible interfaces with reusable React components and maintainable TypeScript. Because I understand the Node.js, Express and MongoDB side too, the UIs I build fit cleanly with the APIs behind them.
