Profile

A decade of production software

I'm a senior engineer with close to ten years of shipping production software, now focused on full-stack web development and AI-powered applications. My work has mostly been operational: tools that people use all day to run a business — tracking repairs, logging incidents, dispatching rides, managing appointments — where correctness and uptime matter more than novelty.

I take a project end to end: database schema and API design through to the responsive frontend. Recently that's meant integrating LLMs into real workflows — Claude and OpenAI-powered agents handling customer interactions and automating support — plus real-time interfaces built on streaming and WebSockets. I care about clean code, good developer experience, and software that is genuinely useful.

Pasalubong Exchange

A marketplace that puts micro, small and medium enterprises online — built native for Android, with an active base of sellers listing products.

Remarkable Roxas city guide app

The official digital platform for Roxas City, Capiz — sights, events and local delicacies for visitors and residents of the Seafood Capital of the Philippines.

Shutl shuttle hailing app
Flutter · Mapbox

Shutl

Ride-hailing mechanics applied to public shuttles: instead of booking a car, passengers flag their location so the shuttle driver knows where to stop.

Viaje ride booking app
Flutter · Firestore

Viaje

Ride booking with a paired driver app, running on a real-time Firestore backend with Google Places for pickup and destination search.

Nex.Us Wi-Fi sharing app

Pasalubong eXchange enables micro, small and medium enterprises to connect with their customers online, presenting a unique and efficient e-commerce experience.

Built with native Android development. The platform hosts an active base of sellers listing products.

The official digital platform for Roxas City, Capiz — a guide to sights to see, places for fun, events to join and delicacies to eat. Whether you're visiting the Seafood Capital of the Philippines for the first time or coming home after a long time away, it's built to guide your stay.

Built with Flutter and Firestore.

Shutl — Shuttle Hailing

Shutl works like a ride-hailing app, but instead of booking a car you flag down your location so the shuttle driver knows where to pick you up.
