Biography

I graduated in 2026 with an Engineering Degree (Diplôme d'Ingénieur d'État) in Computer Systems Engineering from École Supérieure en Informatique 08 Mai 1945 (ESI-SBA), Sidi Bel Abbès, Algeria. I am now a Master 2 student at Université Paris-Saclay.

My academic journey has given me strong foundations in networking, operating systems, IoT, and cryptography/security. Outside the classroom, I actively practice offensive security through CTF competitions, build home labs for Active Directory pentesting, and develop Python security tools.

I aim to bridge the gap between networking and cybersecurity — understanding how enterprise infrastructure works so I can better secure and audit it.
