Freelancer profile translated to English.
Back to original languageAbout Gaetan
Passionate about new technologies, I decided to retrain more than 10 years ago in the IT field.
I therefore moved from Marketing to IT.
Throughout these years, I held the position of "SYSTEM & NETWORK ADMINISTRATOR" within different organizations, with a significant scope of responsibility.
My interest has focused particularly on cloud-related technologies, IaC tools (Infrastructure as Code, Terraform), and automation and CI/CD tools (Ansible, Vagrant, Packer, Puppet, Chef, Gitlab, Github, Jenkins...).
As I did not have the opportunity to exclusively practice these activities in my various experiences, I decided to embark on the freelance adventure.
This choice was necessary in order to dedicate myself solely to these activities and thus be able to offer my services and work with teams specialized in this field.
