About

Software that quietly works.

I'm a software developer based in Davao City, Philippines. I work remotely with teams around the world — founders, product squads, and indie builders who want someone who can own a problem end-to-end and deliver calmly.

My day-to-day is full-stack: TypeScript and React on the front, .NET / Node on the back, with Supabase or Postgres when data needs to persist. Lately I've been leaning into AI-assisted workflows — not as a gimmick, but as a faster way to ship the boring parts so you can think about the interesting ones.

  • Full-stack comfort

    Frontend, backend, infra, deployment. Happy owning a problem end-to-end instead of throwing it over the wall.

  • Calm delivery

    Honest scopes, shipped on time. I'd rather deliver a small thing that works than a big thing that doesn't.

  • AI in the loop

    I use AI to ship the boring parts faster — not as a gimmick, but as a real force multiplier on everyday work.
