# 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 Shared Tech Intern at ING Hubs Philippines.

## 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.
