About

Curious about tech since I was six — and that spark has only grown.

These days I build software, games, and never-ending AI-powered mechanics — with a soft spot for pixel art. I'm a CS grad from UW, class of 2024, and I'm always learning whatever comes my way, whether that's a new framework, a tricky bug, or an entirely unfamiliar domain. When I'm not coding, you'll find me hooping or in the gym.

Fluent in English and Filipino/Tagalog.

The next project

Space reserved — I'm always building, and this shelf keeps growing.

Game development

A new world I'm exploring.

I've always loved games, and building them has been a fun way to keep learning. I'm still early in the journey, but every project teaches me something new.

Next game — in the works

Applying everything I learned to a more polished project. Details, screenshots, and a playable build are on the way.
