Freelancer profile translated to English.

Description

Network engineer with solid experience in demanding international environments, I design, secure, and optimize complex network infrastructures, from LAN/WAN to the Datacenter.

I am involved in:

the evolution and transformation of multi-site network architectures,

the industrialization of equipment deployment via Cisco Catalyst Center (DNA Center),

the security of wired and Wi-Fi network access (implementation of 802.1X, Clearpass, Radius, segmentation, VLANs),

the administration and migration of Aruba Wi-Fi solutions (UXI, Airwave, Central),

Wi-Fi coverage and performance audits with Ekahau,

Palo Alto firewall management (rules, interfaces, traffic),

and maintaining Datacenters in operational condition (traffic matrix, FEX, Nexus 7K to 9K migration).

After several years of experience as a network engineer within a group IT department, I wish to broaden my scope of intervention through freelance or payroll-carrying assignments.

Open to opportunities in the Ile-de-France region or remote work, I am available to collaborate with IT service companies, end clients, or project teams looking for an immediately operational, autonomous, and proactive profile.
