Freelancer profile translated to English.
Back to original languageAbout Quentin
After more than 5 years in IT consulting firms with extremely varied missions, I am now looking for freelance opportunities. What drives me is being at the center of network and security architecture projects. I have had the chance to work in many different sectors, and I hope to discover others as it is very enriching for me. I am currently very interested in automation and AWS Cloud (DevOps/FinOps perspectives) on which I am actively training. Being curious by nature, I have always sought new topics, projects, and opportunities. If you have any, don't hesitate!
