À propos de Lucas

Your network infrastructure needs to be secure, reliable, and ready to scale — without interruption.

I'm a Senior Network & Infrastructure Engineer with 9+ years of hands-on experience in complex, multi-site environments. I help companies design, secure, and automate their network infrastructure so their teams can focus on what matters.

What I bring to your project:
→ Network architecture design: LAN/WAN/WiFi, VLANs, redundancy, high availability
→ Network security: PaloAlto & Fortinet firewalls, VPN, NAC, ACLs, URL filtering
→ Routing & switching: Cisco, Aruba (CCNP certified)
→ Automation & scripting: Ansible, Python, Bash, PowerShell
→ Monitoring: Zabbix, PRTG, Centreon
→ Virtualisation: VMware expert
→ Clear documentation and network diagrams (Visio, Lucidchart)

Recent highlights:
— At Hublot (Switzerland), I designed and deployed the full network architecture for a new HQ and production site — LAN, WAN, WiFi, firewalls, full redundancy — with zero downtime in a critical manufacturing environment.
— At Capgemini, I managed network infrastructure for AREVA and CEA — two of France's most security-sensitive organisations.

I onboard fast, work independently, and leave solid documentation behind me.
