Software Developer — Mobile & Web

I'm a software developer building production mobile apps with Flutter — three live on the App Store and Play Store, and I maintain them full-time: a social cinema platform, a restaurant reservation app, and a field operations tool that replaced paper forms. Lately I've gone full-stack on the web with Astro and Express , shipping a marketing site and custom CMS that a real business now runs on.

Projects

A collection of projects I've built — from full-stack applications to mobile experiences.

Featured Project

K & K's Events

A marketing site and custom headless CMS for an event styling team in Sta. Rosa, Laguna. The owner publishes the gallery, reviews, schedule, and inquiries through a passwordless admin panel — no code, no rebuilds.

ResiboVault

Born from one too many "Bayad ka na ba?" moments. Screenshot a GCash, Maya, or bank receipt — Gemini 2.5 Flash reads the amount, ref, and recipient for you. Search anytime by name or amount. Need to prove a payment? One tap generates a shareable link that expires in 7 days — they see the receipt, not your whole vault.

Keepsake — Memory Archive

An offline-first Flutter app for archiving the objects that shaped you. Take a photo, write why it matters, record your voice while it's still fresh. Organize by collections and tags, swipe through photo galleries, and restore everything silently on a new device — all backed by your own Google Drive.
