As part of a modernization of the IT system of a public sector organization, I led the progressive migration of 9 servers to a newer and more secure environment (8 Linux and 1 Windows).

In parallel, I created 4 complete environments from scratch — Development, Testing, Pre-production, and Production — with 9 configured and deployed servers in each. This represents a total of 36 created and operational servers.

On each environment, I ensured the complete deployment of the Tigre 7 business application, making sure everything worked correctly without interruption for users.

The entire project was carried out step by step, with complete documentation to ensure the longevity of the installation.

System and network administrator, I am involved in the monitoring, administration, and operational maintenance of IT infrastructures in Windows and Linux environments.

My main responsibilities include:

- Monitoring of equipment and production tracking to ensure the availability and performance of the information system

- Administration of Windows and Linux servers (installation, configuration, maintenance, and incident management)

- Configuration and management of network equipment (switches, routers, segmentation, etc.)

- Administration of proxy servers for traffic control and access security

- Management and operation of virtualized environments via hypervisor servers

Projects carried out:

- Implementation of a dedicated VLAN for printers to improve security and network management

- Creation of a technical environment for the deployment of a business application (Tigre 7)

- Participation in cybersecurity projects, including strengthening Active Directory security by following ORADAD recommendations

- Contribution to the overall improvement of the information system's security posture

Organized and rigorous, I contribute to ensuring the stability, security, and performance of IT infrastructures while supporting their evolution.
