Freelancer profile translated to English.

Description

Freelance IT consultant based in Reims, I work with SMEs and associations to structure, secure, and evolve their IT environment.

After 7 years as an IT Manager in the medical sector (ARPDD, Reims), I managed large-scale projects: complete overhaul of the server infrastructure, Microsoft 365 migration, integration of cybersecurity solutions (SOC, firewalls, pentests), IT asset management, and user support.

Today, through AG – ITConcept, I offer this experience to organizations that need an operational and autonomous IT expert, without the constraints of recruitment.
