About Antoine

Freelance Systems and Network Administrator, I work on varied and demanding IT environments, particularly in higher education, IT services, and critical business contexts.

I work on the entire infrastructure operating cycle: operational maintenance, L2/L3 support, monitoring, system and network security, and evolution. I am accustomed to managing complex incidents, intervening in sensitive environments, and implementing hardening and continuous improvement actions to ensure the stability and security of services.

I work on both Windows and Linux systems as well as virtualized, cloud, and hybrid infrastructures. I intervene on identity services, user access, network and security environments, as well as cross-functional services essential for the smooth operation of organizations.

My role is not limited to support: I analyze needs, propose appropriate technical solutions, and support their implementation in multi-site environments. I am comfortable with daily operations as well as architecture, security, and documentation topics.

Autonomous, rigorous, and proactive, I place great importance on communication. I take the time to explain technical choices and their implications, so that the implemented solutions are understood, maintainable, and truly useful to users and teams.

If you are looking for a reliable systems and network administrator to support you on your IT projects, both in operations and infrastructure development, I would be delighted to discuss with you.
