Computer Engineering student at the Polytechnic University of the Philippines (Manila). I ship practical systems: full-stack web, mobile packaging, embedded prototypes, and documentation that another engineer can actually run.
Preference: verifiable behavior over slide-deck claims. If a repo cannot be opened, tested, or handed off cleanly, it is not finished.

| Front-end systems | Vanilla HTML/CSS/JS when the problem is small; intentional UI, not template sludge |
| Embedded | Arduino Mega/Uno, sensing, relays, scheduling, KiCad handoff |
| Docs and evidence | Markdown, architecture notes, screenshots, runbooks, source-linked diagrams |
| Networking / security coursework | Packet Tracer labs, switching/routing basics, Wireshark |
- Prefer runnable demos and clear READMEs over private screenshot dumps.
- Keep secrets and client context out of public trees.
- School projects get product names and setup docs; course credit lives at the bottom of each repo, not as the headline.
