Full-Stack Developer · Based in Philippines
A decade of shipping things that run in production -- web platforms, mobile apps, IoT backends, and the plumbing that holds them together.
About Me
I have spent ten years building software end to end. That usually means a PHP and MySQL backend I designed myself, a REST API layer, an Android or iOS client, and an admin dashboard that somebody actually has to use every day -- so it had better be clear. My work runs across agri-tech sensor platforms, food delivery fleets with live GPS routing, emergency hotline dialers built for rural connectivity, parental-control launchers, document routing systems, and AI-assisted career tooling. Outside of client work I build for curiosity: a browser black-hole simulator running real general-relativity math, a parametric CAD editor, a home-automation hub. I was ranked among the top 21 programmers in the Philippine StackLeague in 2021, and I speak at universities and developer events about breaking into the industry, career development in IT, and staying employable as the field keeps moving.
