With over 20 years of experience in information systems, I support companies in their infrastructure, security, and digital transformation projects.
Open Source Technical Expertise
Specializing in Linux environments (Red Hat, Debian, Ubuntu) and Open Source technologies, I master virtualization (KVM, VMware) and particularly the ProxMox solution, which I have deployed on a large scale in production environments, leveraging the full capabilities of the PVE/PBS suite, including Ceph clustered storage management, LAMP/PostgreSQL solutions, high availability, and disaster recovery platform management. This expertise allows me to work on complex architectures and optimize existing infrastructures.
Automation and DevOps
As an expert in scripting (Bash, Python) and Ansible automation, I design robust playbooks for deployment industrialization and centralized management. I integrate DevOps best practices and CI/CD pipelines (GitLab) to ensure reproducibility and operational efficiency.
Security and Compliance
My in-depth knowledge of cybersecurity (Master's in Cybersecurity in progress) enables me to establish security policies, organize audits and penetration tests, manage enterprise PKIs, and secure systems according to the most stringent standards. I have notably ensured the protection of sensitive medical data for large pharmaceutical groups.
Architecture and Strategic Consulting
I design scalable and resilient architectures by analyzing business needs and technical constraints. My IT Director/CIO experience allows me to understand business challenges and provide strategic recommendations, budget optimization, and technical team coordination.
