Back to original languageAbout Ewen
Expert in network and security infrastructure, I administer and configure modern network equipment—switches, routers, firewalls—in demanding professional environments. I combine this network expertise with mastery of IaC automation (Terraform, Ansible, CI/CD) and AI applied to IT operations (agents, n8n).
As a certified trainer, I also support teams in upskilling on automation, cybersecurity, and streamlining administration processes.
