"We came, we saw, we pwned." That's how I summed up our win at Rage Against the Flag, and it's still how I approach a challenge: show up with the team, look closer than anyone else, and keep digging until the flag falls.

I'm Youssef Sahnoun, a computer science engineering student II2 @ ENSI in Tunis, focused on Cybersecurity & Development. Most weekends you'll find me playing CTFs as captain of team TEZ, where my lane is OSINT: following digital footprints until they lead somewhere, plus forensics and steganography when the board needs it.

At O.S.S.E.C, ENSI's security club, I'm on the technical team as a trainer and design manager, so I get to teach the craft and make it look good too. I've also built 0ffs1de CTF, and I'm writing the forensics and OSINT challenges for OSSEC's Capture the Cup CTF. I ran a Linux Fundamentals workshop for the club, too.

On the engineering side, I spent my internship building ThreatFlow, a threat-intelligence platform that tracks new malware IOCs and CVEs and walks analysts through remediation. I also built Synapse, an operations platform for study spaces that's live in production, plus a full-stack portfolio and store for a Tunisian sculptor, a social network in C, and a Snake clone in raw x86 Assembly. When I learn something, I write it down in FouskaCTF so the next person has an easier time.
