Henri Olivier

With several years of experience in IT, I have evolved from support to system and network administration, to the complete management of an IT department. I spent 5 years within the international group RDM, where I progressively took charge of user support, infrastructure administration, and then IT responsibility for the site. These years have given me a concrete and operational vision of a company's technical needs.

I was also IT Manager for 2 years at TotalEnergies, where I managed the local infrastructure, technical projects, security, and user support. An experience that taught me to manage critical environments, coordinate multiple stakeholders, and remain effective in emergencies.

In parallel, I carried out several additional missions: training students, supporting SMEs, and participating in IT restructuring projects.

Skills:

- Windows / Linux

- Active Directory, DNS, DHCP, Azure, Microsoft 365, Exchange, Defender

- AWS

- High availability

- IP Telephony

- Cisco Expertise (CCNA1 & CCNA2)

- Virtualization (VMWare, Hyper-V, VirtualBox)

- Backups (scripts, Veeam, Cobian)

- Monitoring (Nagios, PRTG)

- Scripting / Automation

- SQL basics

- Administration of third-party tools (Jira / Confluence, Bitwarden, Divalto, SalesForce ...)

My areas of expertise:

- Infrastructure management, maintenance, and optimization

- Implementation, migration, and management of cloud environments

- Securing workstations, servers, and data

- IT projects (restructuring, deployments, upgrades, redesigns)

- Advanced support and complex incident resolution

- Consulting and support on technical choices

- Training, SME support, and IT restructuring projects

If you are looking for someone reliable, responsive, and capable of taking charge of your technical issues, I am here to assist you.
