Summary
👤
Senior🎓
Top SchoolGaëtan Trellu is a seasoned Solutions Architect with 12 years' hands-on experience designing and operating cloud-native and OpenStack platforms, now based in Montreal. He brings deep DevSecOps, Linux and automation expertise, having built Ansible testing frameworks, authored dozens of Ansible modules, and deployed production OpenShift and Kubernetes clusters across VMware, IBM Cloud and bare-metal environments. A long-time OpenStack contributor, his code and roles in projects like Kolla-Ansible and Trove show a practical focus on automation, high availability (Ceph, Masakari) and database-as-a-service edge cases. Comfortable moving between strategy and implementation, he has led technical teams, built CI/CD and patching-as-a-service solutions, and integrated complex ecosystems (Vault, Prometheus, EFK, Harbor). Outside of formal roles he’s an energetic open-source hacker—“just a happy g33k”—who still prefers solving thorny infra problems in the shell.
