About Me

Building practical cybersecurity skills through labs, research, and real-world hardening.

I am developing a strong foundation in cybersecurity with a focus on web application security, Linux server hardening, vulnerability analysis, and secure hosting practices.

My approach is hands-on: I learn by building, testing, breaking, documenting, and improving. This portfolio highlights my labs, security writeups, certifications, and projects.
