Get to know me

A bit about me

I'm a Computer Science student majoring in Software Technology at De La Salle University, graduating February 2027. My work spans full-stack web development, secure application design, and database systems — and lately I've been leaning hard into cybersecurity.

My favorite project so far is a secure payroll web app built with role-based access control, salted password hashing, brute-force lockout, and full audit logging — basically, I like building things that are hard to break into.

Outside of code, I'm based in Rizal, and I'm almost always listening to R&B songs and Kiyo while I work.
