System and Security Engineer – Reliable and Controlled Infrastructures
A multidisciplinary digital engineer, I support VSEs/SMEs, associations, and freelancers in the implementation, security, and optimization of their IT infrastructure.
My goal is twofold: to provide you with robust technical solutions and to give you the keys to understand them.
My areas of intervention:
Server & Storage Administration: Deployment and configuration of NAS (TrueNAS, OMV), database management, secure synchronization and backup.
Network & Security: Implementation of remote access (WireGuard, ZeroTier), performance monitoring (Netdata), access management, authentication (OAuth 2.0), and web application security.
System Administration & Maintenance: Windows, Linux (Debian/Ubuntu), and macOS environments. Diagnosis, troubleshooting, and optimization.
With experience at Valeo (security and deployment via Kubernetes/GKE) and Bioserenity (Agile methodology), I combine engineering rigor with real pedagogical skills. I simplify complex concepts so you maintain full control of your tools, without unnecessary jargon.
