Back to original languageAbout Zacharie
Network & Security Engineer, I support companies in securing, improving the reliability, and evolving their infrastructure.
I mainly intervene on:
- resolving complex network incidents
- securing access (VPN, firewall, segmentation)
- infrastructure migration and evolution projects
I have notably contributed to:
- the migration of an HPE datacenter to Cisco without service interruption
- the implementation of a backup site with redundant infrastructure
- securing and ensuring high availability of applications via F5 BIG-IP
I have worked in demanding environments (Sateba / Vossloh, Servier, IMA, SGP), which has allowed me to develop a reliable and service continuity-oriented approach.
Main Technologies: Fortinet, Cisco, HPE, Aruba, F5 BIG-IP
👉 My goal: to provide you with effective solutions, quickly, without complicating your infrastructure.
