Freelancer profile translated to English.

Description

I am Lucien, a systems and network administrator with 7 years of experience in managing, securing, and optimizing IT infrastructures. Throughout my career, I have ensured the proper functioning of operating systems (Windows Server, Linux), managed physical and virtualized servers, and administered enterprise networks, including configuring equipment (switches, routers, firewalls) and implementing VLANs, VPNs, and security policies.

I ensure the availability, performance, and security of critical services, while supporting the company's technical evolution through migration, virtualization, or cloud integration projects.

Rigorous, proactive, and solution-oriented, I systematically document my interventions while providing level 2/3 support to users and internal teams. I constantly stay updated on new technologies and industry best practices to evolve the infrastructure reliably, securely, and efficiently.
