About Axel

Looking for a versatile profile to maintain, secure, and evolve your IT infrastructure? As a Systems and Network Administrator, I support companies in the daily management of their infrastructure and the guarantee of service continuity.

My generalist profile allows me to have a global vision of your information system. I intervene as much in resolving complex incidents as in administering hosting infrastructures. My goal is to provide you with a stable, secure environment dimensioned according to your needs.

What I concretely bring you:

Server & Hosting Administration:
Deployment, management, and monitoring of servers and VPS. Evolutionary maintenance interventions.

Network & Web:
Configuration of reverse proxies, traffic routing, and operational maintenance (MCO).

Virtualization & Containerization:
Implementation and management of virtualized environments and containerized stacks (Docker) to optimize your resources.

L2/L3 Technical Support: Handling infrastructure incidents, problem-solving, and technical support.

My typical deliverables:

Audit, security, and preventive maintenance of your servers (Linux/Windows).

Infrastructure evolution operations (storage upgrade, migration, resizing).

Deployment of robust web hosting solutions.

Let's discuss your hardware and software needs to build or consolidate an infrastructure you can rely on 100%.
