What I'm looking for

I’m seeking a permanent position in cybersecurity or cloud to contribute to the security and supervision of critical infrastructures, delivering SOC detections, threat intelligence monitoring, and reliable monitoring/incident reporting.

I’m a cybersecurity & cloud engineer with 3 years of work-study experience at GRDF, specialized in SOC operations, cybersecurity tooling, and cloud environments. I deploy and configure SEKOIA.IO and build detection content (SIGMA/CTI/anomaly rules), integrating sources with Microsoft Sentinel, Microsoft Defender, and CrowdStrike.

I also support continuous supervision by creating synthetic monitoring scenarios, administering platforms (Iplabel/Ekara), and improving incident and alert reporting for SOC teams with Splunk and PagerDuty. My work spans cyber threat intelligence monitoring (CVE/ANSSI bulletins, CTI feeds), regulatory follow-up (NIS2, LPM, ANSSI guidelines), and security asset management with strong technical documentation habits.
