Back to original languageAbout Vincent
Systems and infrastructure administrator with 3 years of experience in a production Linux environment, including 2 years within a large banking group. Specializing in Linux administration, automation, and infrastructure security.
I primarily work on system administration tasks, infrastructure deployment and configuration, monitoring, automation (Bash, Ansible), and implementing best security practices (CIS Benchmark, NIST).
Outside of my professional experiences, I independently build infrastructure projects — Kubernetes clusters, 3-tier AWS infrastructure with Terraform — applying the same security standards as in production.
