// About Me

WhoIAm

Driven fifth-year Computer Security student with hands-on expertise in offensive security, malware analysis, cryptographic implementation, and large-scale Linux infrastructure. I founded Watheeqa, Algeria's qualified electronic-signature SaaS for the legal sector, and won 1st place at the national “Coding Master” programming competition. I'm passionate about understanding how systems break in order to build them stronger — across penetration testing, reverse engineering, and full-stack secure development.
