04ABOUT
Denmark Crisostomo

I'm a full-stack developer based in Metro Manila. I care about the parts of software people don't see — schema design, auth, performance budgets — because that's what makes the parts they do see feel effortless.

Most recently I designed and shipped Holy Protocol end to end. Before that: a threat-intelligence platform, automation tooling, and a handful of products built to be fast, secure, and maintained — not just launched.

05 — CONTACT

Let's build something that lasts.

Open to full-time roles, contracts, and collaborations. The fastest way to reach me:
