About
I'm Raphael, a Cebu‑based AI Full‑Stack Engineer who turns product ideas into production‑ready software in weeks—not quarters.
My stack spans TypeScript, React/Next.js, Node, PostgreSQL, and Flutter, but my unfair advantage is strategic AI integration. From single‑shot LLM content calls to multi‑agent LangGraph workflows, I weave machine intelligence into every layer so your product feels smarter with every click.
The Full Story
Combine a Computer‑Science‑cum‑laude foundation with years of remote SaaS delivery, add an obsession for Gen‑AI tooling, and you get a builder who codes at human speed and thinks at AI speed. I've led front‑end migrations, shipped social platforms, and even wired up crypto wallets—always focusing on user‑centric polish and measurable impact. When I'm not coding, you'll catch me reading about agentic architectures or jogging Cebu's seaside loop.
