🏗️ Data Platform Availability

Ensured continuous operation of BI (MicroStrategy) and database (MySQL, Vertica) environments — zero unplanned interruptions for critical data flows for business teams.

🔐 Security & Compliance

Strengthened park security: centralized update management (WSUS, GPO), antivirus protection (Sophos), and network access security via VPN/Barracuda firewall — reducing threat exposure.

⚙️ Operational Reliability

Automated recurring operational tasks (PowerShell, Bash) and implemented proactive monitoring (Centreon) to anticipate incidents before user impact.

☁️ Virtualization & Cloud

Managed virtualized (ESXi, vCenter) and Azure cloud environments, providing a scalable and resilient infrastructure adapted to the company's data needs.

🔄 Continuity & Traceability

Managed incidents and requests via Jira with rigorous technical documentation — reducing resolution times and facilitating team skill development.

🖥️ User Park Availability

Ensured service continuity on a multi-OS (Windows, Linux, Mac) park by managing level 1 and 2 incidents — reducing downtime and maintaining end-user productivity.

🚀 Scalable Deployment

Managed the deployment of Munki on the macOS park, enabling centralized and automated software distribution — reducing manual interventions and accelerating application updates.

🔐 Workstation Security

Maintained a consistent security level across the entire park through antivirus management (GData, Kaspersky) and VPN access (Cisco) — limiting exposure to risks for all university users.

🎯 Service Quality & Traceability

Structured request and incident management via GLPI (tickets, forms, templates) — improving support traceability and user satisfaction through controlled processing times.

📡 Remote Support

Provided effective remote support (TeamViewer, SSH) to quickly resolve incidents without travel, regardless of the user's technical profile.
