About.

Joshua Rio
Open to work

I build real things that get deployed.

I'm a BSIT graduate from STI College Tanauan, based in Batangas, Philippines. My work includes a real-time Android roadside assistance app, a production corporate website, and a local AI document chatbot.

I don't just follow tutorials. I deploy things, secure them, and make them fast. I'm currently looking for a professional role — open to Metro Manila or remote.
