Product Engineer — Web & Mobile
React · React Native · TypeScript · Node.js
I design and ship web and mobile products end to end—from interfaces and APIs to data, integrations, and release. I turn complex business workflows into clear, reliable systems.

A gamified personal-finance app that turns budgeting, debt, and savings into an RPG progression loop — 100% offline, zero data collection.
Multi-tenant POS and inventory platform built for web and mobile, with tenant isolation and server-authoritative stock workflows.
A trading journal that imports activity and turns it into useful performance, risk and drawdown analytics.
A cross-platform folklore app delivering Filipino stories in text and audio, with more than 50,000 downloads.
Product engineering, from architecture to release.
I'm a product engineer with 8+ years building web and mobile products across retail, finance, operations and enterprise workflows. I work the full delivery lifecycle—requirements, architecture, APIs, data, release, and the maintenance that keeps a product reliable in production.
I currently lead frontend and mobile as a Software Engineering Team Lead, making the architecture and technical decisions while staying hands-on in the code. The work I take on tends to be the hard part: complex operational workflows, cross-platform delivery, offline and mobile constraints, authentication and third-party integrations, multi-tenant systems, financial and transactional logic, legacy-system modernization, and production reliability.
