About Me

I am a Computer and Communication Engineering student with hands-on experience in full-stack development and cybersecurity.

I build real-world web applications, backend APIs, and security-focused systems including Web Application Firewalls and vulnerability scanners. I actively participate in Capture The Flag (CTF) competitions to understand real attack techniques and defensive strategies.

My focus is on developing systems that are not just functional, but secure, scalable, and built with strong backend architecture.
