Back to original languageAbout Gérémy
Network, Telecom and Cybersecurity Project Manager with over 25 years of experience in IT infrastructure, including 10 years in technical project management.
I have supported telecom operators and large corporations in the design, evolution, and deployment of LAN, WAN, SD-WAN, Wi-Fi, VPN, and firewall infrastructures.
I am involved in the entire project cycle: understanding technical and functional needs, scoping, planning, coordinating internal and external teams, risk management, budget and deadline monitoring, acceptance testing, go-live, and handover to operations teams.
My background includes 8 years in telecommunications and networks, as well as 3 years at VMware and Dell in virtualization and infrastructure environments.
Since 2021, I have strengthened my specialization in network cybersecurity: segmentation, filtering, security policies, NAC, monitoring, SOC, and infrastructure security.
