Network & Systems Engineer | Infrastructure, Security & Virtualization

Role and background

Specializing in the administration of complex network infrastructures and system security, I have extensive expertise in Cisco, FortiGate, PfSense, Windows Server, ESXi/VMware, and Microsoft 365. With extensive experience in demanding environments—including telecommunications, managed services, and international projects—I combine technical rigor, operational autonomy, and the ability to collaborate effectively with both French- and English-speaking counterparts.

Professional Experience

Network Engineer (TSC Network)

Since 2023

Orange Business Services

Projects in France and Mauritius

At Orange Business Services, I provided technical support and managed the operations of network infrastructures for local and international clients in the telecommunications and digital services sectors.

I prepared, configured, and commissioned network equipment (routers and switches), ensuring the stability, performance, and availability of services, particularly on BVPN, Flexible Internet, and Business Voice projects.

As the equipment administrator, I effectively diagnosed, analyzed, and resolved incidents with a high first-contact resolution rate, while escalating complex issues and coordinating investigations with specialized teams.

I also mentored and assisted the Level 1 support team to strengthen their skills and optimize incident management.

Committed to continuous improvement, I implemented standard and complex changes, handled day-to-day administrative tasks (user management, SLA monitoring, service supervision), and collaborated regularly with international counterparts to ensure a functional, stable, and operational network for customers.

IT Support Expert

2021–2023

At an outsourcing company

Project implementation in France

As an IT Expert at Almerys, I was responsible for deploying IT services and ensuring their smooth operational functioning.

I handled support tickets according to priority and assisted users remotely (via Skype, phone, AnyDesk, TeamViewer) or in person on-site.

I ensured service quality by effectively resolving incidents related to the network, workstations, email (Outlook), Office applications, and operating systems.

I performed comprehensive maintenance on the IT infrastructure: repairs, system reinstallations, replacement of hardware components (PCs, servers, motherboards, etc.), as well as the administration of virtual servers running on ESXi, VMware, and Hyper-V, with infrastructure monitoring via Zabbix, Smokeping, and Latency.

I also managed specialized servers: Tournéo attendance tracking, Synology NAS (files and access rights), email (hMail, Office 365, OVH), as well as Active Directory administration (user accounts, groups, GPOs, DNS, DHCP).

Finally, I assisted with the installation, configuration, and administration of new equipment (servers, switches, routers).

Through direct collaboration with the Almerys teams, I ensured stable, reliable operations that met the client’s requirements.

IT Technician (Help Desk)

2019–2021

Harel Mallac Technologie

Local and Mauritian Project Experience

As an IT technician and network and system administrator at Harel Mallac Technologie—a company specializing in IT, infrastructure, security, building automation, and fintech—I provided customer support for Madagascar and Mauritius.

I worked at Level 1 to diagnose and resolve incidents over the phone or via email, particularly regarding email (Outlook), systems, and software, using remote access via TeamViewer or AnyDesk. At the Level 2 level, I performed on-site support, including inspecting equipment (PCs, network cables, switches, routers, servers), as well as setting up and configuring hardware.

I was also responsible for installing and configuring servers according to client needs (Active Directory, DHCP, etc.), performing weekly maintenance, and ensuring their availability.

Through rigorous incident management and the implementation of appropriate solutions, I contributed to the optimal and uninterrupted maintenance of IT services, while enhancing the quality and efficiency of the deployed infrastructure.

Harel Mallac Technology

Local and Mauritian Projects

While working as a technical intern at a Malagasy company specializing in IT services and hardware sales, I participated in the implementation of two Active Directory sites that were replicated and interconnected via an IPsec VPN tunnel running on Windows Server 2012 R2.

This experience allowed me to strengthen my skills in system administration, network security, and IT infrastructure deployment.

Dedicated and meticulous, I contributed to the establishment of a reliable and secure environment, while developing a practical understanding of the challenges associated with managing enterprise networks.
