Description

Securing, making reliable, and automating IT infrastructures for SMEs and associations.

With 20+ years of experience in system administration and infrastructure management, I support organizations looking to secure and automate their IT systems without increasing their operational burden.

Specifically, I help you to:

• Audit and harden your infrastructure (Active Directory, Linux/Windows servers, websites) — vulnerability assessments, hardening, compliance.

• Automate your administrative tasks (backups, deployments, reporting, supervision) to eliminate manual operations and improve reliability.

• Industrialize your processes in Python, with or without AI components: workflow automation, API integration, data extraction and analysis.

• Containerize and make your deployments reliable (Docker) with continuous integration and automated security checks.

• Supervise your infrastructure in real-time (monitoring, alerting) to anticipate incidents.

My approach: understand the existing system, identify the root cause of the problem, deliver a documented and maintainable solution.

🎓 Currently pursuing certification as a Secure Infrastructure Administrator (RNCP level 6).
