About.

Joshua Rio
Open to work

I build real things that get deployed — from bare metal to cloud.

I'm a BSIT graduate from STI College Tanauan, based in Batangas, Philippines. My work spans full-stack software development and hands-on computer hardware servicing: from deploying real-time Android apps and AI chatbots to custom PC assembly, laptop repairs, and thermal repasting.

I don't just follow tutorials. I assemble hardware with precision, write clean code, secure production domains, and make systems fast. I'm currently looking for a professional role — open to Metro Manila or remote.
