Certified Linux expert in Lyon: servers, containers and deployment
Sébastien Mizrahi is a software architect and Cisco Linux 1 certified Linux expert (LPIC-1 level) in Lyon. He designs, secures and maintains Linux environments, from the web server to container orchestration.
An application is only as reliable as its infrastructure: configuration, security, backups, reproducible deployment.
From the Debian servers I installed as a student to today's containerised services, Linux is the foundation of all my projects.
