About Me

Systems and Network Administrator specialized in DevOps / Infrastructure as Code, I manage, build and automate reliable, secure, and uninterrupted IT infrastructures.

Using modern, proven tools, I transform your IT into a stable, autonomous, and resilient system designed to last.

This means fewer incidents and breakdowns, greater day-to-day stability, enhanced monitoring and security, continuous updates, flexible, scalable configurations, a system that grows with you.

I work with SMEs and local governments that want access to cutting-edge IT without complexity, companies undergoing modernization that want to secure and automate their environments, or entrepreneurs who want to entrust their IT systems to a competent professional.

Skills

  • Management of Kubernetes clusters

    Setup and management of services based on Kubernetes clusters. Deploy and maintain efficient, cost-effective and highly available IT infrastructures with centralized configuration.

  • Management of monolithic servers

    Full configuration of application servers like GLPI, Wordpress or Nextcloud. Management of dependencies and access, database, maintenance plus network setup (SSH, NAT, DNS, firewall) and scurity (TLS certificates, monitoring).

  • Infrastructure-As-Code Deployments

    Infrastructures or applications deployments using centralized code files. Designing manifests and Dockerfiles for Kubernetes and Docker. Configuring, securing, and improving applications using a GitOps approach.

  • Multi-environment architectures implementation

    Code is deployed across multiple environments (Develop, Staging and Production) to allow testing and measuring the integration of new application features before it goes live.

  • Security Enhancement

    Enhancement of clusters security with NetworkPolicy traffic rules, limited attack surfaces with optimized base images, RBAC rules, service accounts, or kernel isolation tools such as AppArmor, seccomp, or SELinux.

  • Windows Administration

    Management of Active Directory, Group Policy Objects (GPOs), and Windows services, Workstation preparation, MDT deployment, and Office 365 license management, Inventory management, user support and troubleshooting, PowerShell automation.

  • GitOps using Argo CD

    Deployed the Argo CD application using the official Helm chart with a customized configuration (HTTProute, Secrets, TLS certificate). Implemented continuous deployment pipelines between Git and Kubernetes with automated synchronizations.

  • Helm Deployments

    Deployments of Kubernetes Add-ons and Apps like Calico, Traefik, MetalLB, Metrics Server, Prometheus Stack, Wordpress, Harbor or Gitea using Helm charts integrated with Argo CD to standardize installation, simplify updates, and enhance cluster maintainability.

  • IA SLMs and LLMs Models

    Deployment of private Artificial Intelligence solutions based on open-source models (Llama, Mistral, Gemma, Qwen, Nemotron) using Ollama's library, allowing locally hosted containerized AI models to be connected to internal applications without external dependencies on cloud infrastructure.

  • ⚙️ Ansible SysOps Administration

    Automation of system administration tasks using Ansible, covering monitoring maintenance, updates, and operational checks on Windows and Linux infrastructures.

  • ⚙️ WireGuard-Based Secure Access

    Installation and configuration of the open-source WireGuard VPN to secure access to IT environments in a simple and efficient way. WireGuard operates through a silent interface that does not respond to intrusive port scans.

  • ⚙️ Docker Containerization

    I prioritize containerization using Alpine Linux or Chainguard images to benefit from lightweight, fast, and secure systems. Their minimalist composition reduces deployment times, improves overall performance, and limits the attack.

    🔒 Cybersecurity

    Increase the cost of intrusions for attackers. Integrate the latest security practices into every stage of projects. Set up monitoring systems and apply strict firewall rules. Restrict and control the tools used and raise employee awareness of good security practices.
