Profile

Currently pursuing a Master's in Information Systems Management (GSI) at Paris-Dauphine University, I am a Systems Engineer with over 6 years of experience, including more than 3 years at Université Paris-Dauphine. My expertise covers web server administration (IIS, Apache, Nginx), development (PHP, HTML, CSS, Python, MySQL) and automation (Ansible, PowerShell, Bash). I also have strong skills in virtualisation and high availability (Hyper-V, Proxmox), containerisation (Docker), and AI solution deployment (LLM, RAG). My skill set extends to Windows Server administration (AD, DNS, GPO) and Linux Debian, monitoring (Nagios Core, CheckMK) and backup (Veeam Backup, Proxmox Backup). I apply a DevOps approach to optimise infrastructure and aim to grow into a role with greater technical and managerial responsibility.
