Software engineer for the zero to one.

DSCF2597 · Tokyo

I want to be in the trenches with you. I’m happiest on a small, ambitious team: talking to customers, shipping fast, and seeing what my work actually changes.

I’ve done it as a founder, as an early engineer, and as a product manager, from the first schema to the server it runs on. Give me a hard problem and I’ll treat your company like it’s mine.

I’m looking for the next startup to join. See the work, or email me.

Selected work

  2. Cash Captain social card: the otter mascot beside the quick entry formCash CaptainThe personal finance tracker I finally use every day, and the app I open most after my AI apps. It’s fast, keyboard first and natively multi-currency, and built for couples and households to run their money together.

  4. Cart AI App Store screenshots: a live grocery budget, a price tag scan, an over budget alert and AI cart suggestionsCart AII built the core backend and scaled it to over 50K downloads. Snap a price tag and it reads the price, converts the currency and warns you before you go over budget.

About

I got into building products through trading. My first one was the screener I wanted for my own trades, and then other people started using it. Building something, putting it in front of people, and watching what they do with it is still the part I like most.

I studied computer science at the University of the Philippines Diliman. I still trade, and I’m interested in living intentionally and the never ending cycle of getting better at my craft.

Mostly TypeScript, Go, React, Svelte, PostgreSQL and AWS.
