Summary
🤩
Rockstar🎓
Top SchoolSébastien J is a DevSecOps engineer with 13 years of experience blending systems, network and security expertise across military, consultancy and enterprise environments. Trained in the French Air Force, he brings operational rigor and leadership to complex SI architectures, from datacenter interconnects to highly available DMZs and Big Data stacks. He has driven sysops/devops at scale—managing hundreds of VMs and containers, Kubernetes, ELK, AWS and automation tools—while embedding strong cybersecurity practices and NIS-level controls. Comfortable translating between technical teams and management, he has steered security architecture decisions and produced hardening guides adopted across organisations. Now at EDF, he continues to combine hands-on engineering with a penchant for knowledge sharing and pragmatic, consensus-driven design. An uncommon asset is his background combining military discipline with deep offensive/defensive cybersecurity experience from his time at LEXSI/Orange Cyberdefense.
