About

I help teams turn ideas into reliable, maintainable software. I work end‑to‑end — architecture, APIs, data, UI — with a focus on clarity and shipping.

Principles

  • Ship small, iterate fast.
  • Choose boring tech when it matters.
  • Automate the repeatable.
  • Measure, then optimize.

Focus

Backend, frontend, and a bit of DevOps. I enjoy clean APIs, thoughtful UX, and systems that can grow without drama.

Skills

Comfortable across the stack; here are tools I use often.
