Back to original languageAbout Olivier
With over 15 years of experience as a Systems and Networks Administrator, I help companies secure, automate, and supervise their IT infrastructure for better performance, reliability, and peace of mind.
I work on Linux systems (Debian, Ubuntu) and Windows Server, virtualization (VMware, Proxmox), as well as network management (TCP/IP, LAN, Wi-Fi, VLAN, VPN). I also implement backup solutions (Veeam, Acronis) and containerization (Docker) to ensure data availability and protection.
DevOps-oriented, I deploy automation solutions to reduce errors, accelerate production releases, and optimize costs. Python and Bash are my preferred tools for developing scripts, orchestrating tasks, and designing custom solutions.
Supervision and monitoring (Zabbix, Centreon) are among my key expertise: proactive incident detection, performance tracking, and resource optimization to anticipate problems before they become critical.
Always staying updated, I also explore the contribution of AI applied to IT, particularly with the development of a business chatbot (ITSM), aimed at simplifying data access and improving the productivity of support teams.
Examples of missions:
- Implementation of supervision (Zabbix, Centreon): dashboards, proactive alerts — 40% reduction in critical incidents.
- Migration / deployment of clusters (VMware → Proxmox): cost optimization, better flexibility.
- Automation with Python / Bash: deployment scripts, inventory, backup — immediate productivity gains.
- Development of an ITSM chatbot (AI + iTop): simplification of data access, productivity gain.
- Outsourced IT management: support for SMEs without an IT team, guaranteed service continuity.
