About
I build products end to end, schema to interface, and I have spent the last two years doing it as a founder; which means every technical decision I made had a customer attached to it.
I love building things from 0 → 1, taking ideas that start as sketches or late-night thoughts and turning them into real, working products. I thrive in fast-paced startup environments, where things move quickly, ownership runs deep, and every decision matters.
I run Garaje, a two-sided marketplace for the automotive community in the Philippines, from Los Angeles. I also ship client work and side products. In all of it I am the person writing the code, not the person reviewing someone else's.
What I care about is the loop: what users need, what the system can express, and what the business can sustain. Most of my best decisions have been deletions.

Frontend Design Engineer · DigiPH
Designed the end-to-end interface for the Philippines' national nutrition surveillance platform, built with the National Nutrition Council. Cited in an official implementation commitment.
Axlecore
2026Founder, design and engineering · Axlecore
Site and lead system for my consultancy. A free-audit funnel on Convex with token-gated confirmation pages, so a thank-you page cannot be reached without a real submission, and lead qualification captured as structured fields rather than a free-text message box.
Nintroller
2026Personal project
An NES controller simulator with real-time input logging and cheat code detection, dressed as a CRT terminal. Built test-first: sixteen suites at 82% line coverage, fully keyboard operable, with an emulator-style layout on mobile and the classic one on desktop.
Daydream Hero
2025Co-founder and lead developer · Independent
A retro-inspired endless runner built with my brother as an indie duo. Started as a RevenueCat hackathon entry and became a real game.
Portfolio 2025
2025Designer and engineer · Independent
The portfolio this one replaced. A dark, atmospheric site with a CRT overlay, a fluid cursor and particles, kept live so the decision to delete all of it stays legible.
AIX Promptplay
2025Personal project
A client-side playground for running the same prompt across multiple language models and comparing the results side by side.
Frontend Software Engineer · XP Network
A live cup tracker for a beer pong tournament in Texas, built as a companion gadget for the XP Network platform and shipped to both app stores.
Payborit

Established the design language for a Filipino payments platform across its merchant web portal and consumer mobile app, and built the portal's frontend on Laravel.
DigiPH Buy2Play
2022UI/UX Designer · DigiPH
Interface design for an online gaming platform at DigiPH: the player-facing web app people sign in to and play on, plus the landing pages selling both the web and mobile products.
