# whoami

I am a Computer Science student at DLSU majoring in Network and Information Security. I focus on cybersecurity and the intersection of backend engineering, DevSecOps, and automation, designing systems where reliable full-stack architecture meets proactive security.

Currently, I balance my studies with my role as a Software QA & Machine Learning Specialist at DeckTradr, where I train custom ML models for image recognition and conduct rigorous QA across platform builds.

## focus

  • -Cybersecurity: offensive security, ethical hacking, vulnerability analysis, and penetration testing.
  • -Infrastructure: DevSecOps pipeline automation, cloud, and backend engineering.
  • -AI & Workflows: machine learning and AI-enabled tools for developer productivity.

## interests

Outside of software engineering and cybersecurity, I spend my time running, playing badminton, reading books, studying German, and listening to music.

Security tooling

Hybrid SAST + DAST scanner that audits LLM-generated ('vibe-coded') web apps for the architectural blind spots AI codegen tends to leave behind. Statically greps for hardcoded secrets, unauthenticated routes, and weak JWT config, then dynamically fires live requests to catch IDOR, rate-limiting gaps, and verbose error leaks — scoring every finding with a built-in CVSS v3.1 engine.
