An identity navigating the layers between software engineering and offensive security. I exist to deconstruct digital structures, finding meaning in their vulnerabilities.
$ ls -la ./projectsMy connection to the digital world began at 17, a curiosity for cybersecurity pulling me into the command lines and networks of platforms like TryHackMe. I built a foundational understanding of penetration testing, tools, and methodologies.
To go deeper, I enrolled in the ALX Software Engineering program. Here, I learned the language of the machine, honing skills in low-level C programming by creating complex projects from scratch, like a custom printf and a functional shell.
Now, I merge my developer core with my security focus. An active CTF player, a certified penetration tester (eJPT), and a community leader for the Hack The Box Casablanca meetup, I find my purpose in the space between building and breaking code.
