About

Born between cultures,
designing for humans.

Grew up between California and the Philippines — caught between two worlds, which taught me more about empathy and communication than any design school could. That experience shaped how I listen, how I build, and what I believe design is actually for.

I'm a product designer with a systems mindset and a stubborn belief that every decision in a product should have a reason behind it. I'm also a parent to two daughters who remind me daily that the best products are the ones that feel effortless.
