03 / Experience

From the fieldto the classroom.

Telecoms taught me how networks work in practice. Cybersecurity took me into architecture. Today, I also share that experience in the classroom.

Since June 20202020

SNS Security

Network & Cybersecurity Engineer

Networks · Cybersecurity · Deployment · Operations

Since June 2020, I have helped businesses design, deploy and operate their networks. I have delivered 283 projects for more than 150 different clients.

My work combines site connectivity with protection of access, systems and applications. FortiGate, FortiAuthenticator, FortiWeb, Netskope, WALLIX and Mimecast are part of my everyday toolkit. In production, I connect security decisions to operational constraints.

  • LAN redesign, VLAN segmentation, FortiGate policies and traffic control.
  • Multi-site connectivity, VPNs, hub-and-spoke SD-WAN, ADVPN and dynamic routing.
  • Strong authentication, FortiAuthenticator and directory integration.
  • WALLIX bastions, privileged access and session traceability.
  • ZTNA and SASE with Fortinet and Netskope; application protection with FortiWeb.
  • Mimecast email security, Cybergraph and DMARC Analyzer.

Alliance Telecom

Network & Telecoms Technician

Telephony · Connectivity · Support

I started in networks and telecoms, working directly with users’ needs: telephony, Internet access, Wi-Fi and network equipment.

Those years gave me a grounding in operations and troubleshooting. They still influence how I design networks: think about their users and the people who will maintain them.

  • Deployment and operation of VoIP telephony and IPBX systems.
  • Installation and support of network equipment, Wi-Fi and carrier connections.
  • Monitoring with Zabbix and Centreon, troubleshooting and customer support.
