01. About Me

I'm a Security Analyst at Orange Cyberdefense, where I focus on detecting and analyzing security threats across complex enterprise environments. My day-to-day involves working with SIEM platforms, EDR solutions, and network detection tools to keep organizations safe.

My core strength lies in blue team operations — from threat detection and security monitoring to log analysis and threat investigation. I'm continuously expanding my skill set, recently diving deeper into purple teaming methodologies to understand offensive techniques and build more resilient defenses.

Outside of work, I actively participate in CTF competitions and platform challenges to stay sharp and keep learning. I believe the best defenders understand how attackers think.
