About
Building things that matter
I'm a backend-focused engineer with 5+ years of experience building production-grade systems. I've worked across the full stack — from Django APIs and Node.js services to React/Next.js frontends — but my core strength is in the server side.
Helping startups and businesses ship reliable software fast. I also build my own products; a handful have reached paying users. Actively seeking full-time opportunities where I can own large technical problems end-to-end.
When I'm not building software, I enjoy hiking and exploring new technologies.
