The developerbehind the code.
I'm a Full Stack Developer who lives in the JavaScript/TypeScript ecosystem. React and Next.js on the frontend, Node.js and Express on the backend, MongoDB as my go-to database. I build things that work at scale and ship them fast.
I'm an active open source contributor — 35+ merged PRs to projects like OpenAI Codex (65k stars) and developer-roadmap (350k stars). I believe the best software is built in the open.
When I'm not shipping code, I'm exploring new technologies, reading about system design, or helping other developers grow.
