Back to original languageAbout Julien
Hello!
I am Julien, a software architect, Python developer, service administrator, and DevOps engineer.
As a developer for over 30 years, I have participated in and contributed to numerous open-source projects, in addition to creating a few myself. I have built several applications from scratch for companies and clients, including the National Education system. I specialize in Python backend development, but I have a long history with C/C++.
As a freelancer, I can offer the following skills:
- Python development, over 10 years of experience.
- Linux/Debian infrastructure setup, with or without Ansible playbooks. I have contributed multiple times to the Ansible and DebOps open-source projects. I am also the creator of the Ansible Roster inventory plugin.
- Setup and administration of GitLab, Proxmox, Grafana, etc.
I enjoy providing simple, maintainable, and effective implementation solutions.
