About

Frontend engineer building the tools content teams rely on.

For 5+ years I've built production web applications with React, Next.js, TypeScript and Node.js — most recently the CMS and Page Configuration Manager behind ABS-CBN's iWantTFC streaming platform.

I own frontend architecture end to end and work closely with backend, design and QA in agile sprints — from a Storybook design system used across squads to payment flows and editorial platforms serving millions of readers.

Lately I've been building with LLMs: a RAG application for semantic search over VOD content metadata, evaluating output quality and designing retrieval pipelines with LangChain, LangGraph, MCP and the Claude API.
