Hi, my name is

Julien.

I'm a Linux System Enginner

An open-source and Linux enthusiast with a passion for clean, automated infrastructure. I enjoy designing reliable systems using tools like Ansible, Packer, and Terraform. I care deeply about monitoring, observability, and system resilience. Always curious, always learning — especially when it comes to improving operations through open-source solutions.

About Me

I have a background in physics and R&D, and I have a interest in the intersection of technology and art. I am currently working as a System Enginner at IBA in Louvain-la-Neuve. Here are a few technologies I've been working with recently:
  • Ansible
  • Docker (Swarm)
  • Python
  • Terraform
  • CheckMK
  • VMware
  • Openstack
  • RabbitMQ
  • Cassandra
