Network & Security Engineer | LAN/WAN Architecture, Firewall, and Cybersecurity

Role and background

I specialize in the design and deployment of complex network infrastructures and am proficient in Cisco, FortiGate, Palo Alto, SD-WAN, and IPsec VPN, with certifications recognized by Fortinet, AWS, and Palo Alto Networks. With experience working on international projects in both French and English, I deliver precise execution with no adjustment period required.

Professional Experience

IT Manager

Since January 2025

At an outsourcing firm

Project Management in France

As the company’s IT Manager, I led end-to-end network and security deployment projects—from planning to production—while managing the technical network and systems team.

I designed the network architecture for new sites (LAN, WAN, VLAN, DMZ, VPN, SD-WAN), conducted site surveys, and implemented the network and security infrastructure (FortiGate, FortiSwitch, FortiAP, Cisco, Sophos).

I configured routing, VLANs, inter-VLANs, DHCP, IPsec VPNs, security policies, and SD-WAN solutions with load balancing, while applying QoS policies for VoIP traffic and implementing network segmentation solutions by department.

I administered the equipment, updated and backed up configurations, monitored and resolved network incidents, and developed comprehensive technical documentation.

In coordination with international teams, I managed user access (FSSO), authentication policies, and web filtering; administered LDAP and file servers (Windows/Linux); and provided training to technicians and users on network and security best practices.

This assignment, which involved international collaboration on technical issues, was completed with excellent results.

Network and Security Engineer

Since February 2018

ETIC Services

Local and French Projects

As a network and security engineer at an IT services company, I carried out projects involving the design and deployment of LAN and WAN network infrastructures for several clients. I conducted site surveys, analyzed client needs, designed the physical and logical network architecture, defined segmentation and improvement plans, developed operational procedures, and configured network equipment while ensuring its proper functioning and network security.

As part of the AGID-PRCI project for the General Administration of Taxes and Public Property in the Comoros, I designed the network architecture for the three sites, configured and deployed the Dell switches (VLAN, VTP, STP, DHCP relay, and snooping) and SonicWall NSA4600 firewalls (routing, NAT, security rules, profiles, and VPN), interconnected the sites via Comores Télécom, installed and configured client workstations, provided support to local users and administrators, drafted technical documentation, and trained network administrators.

For the MA-MWE project (Comorian Water and Electricity Company), I installed and configured HP DL380 G9 servers as well as Windows Server 2012, ensuring a reliable and secure infrastructure.

These projects were carried out in collaboration with engineers from other countries within the group and were completed with excellent results.

Multiskilled Telecommunications Technician

November 2017–February 2018

Telma

Madagascar

As a network technician for TELMA, I configured and installed the network equipment necessary to provide Internet access to residential customers.

These efforts ensured stable and high-performance connectivity while adhering to technical standards and deployment deadlines.

I ensured the quality of the installations and monitored configurations to optimize the user experience.
