Summary
👤
Senior🎓
Top SchoolSebastian Colomar is a Senior Consultant based in Greater Sydney with eight years of deep hands‑on experience architecting, deploying and troubleshooting cloud-native platforms using Linux, OpenShift, Kubernetes, Ceph and related Red Hat technologies. He combines practitioner-level skills (RHEL/RHCOS, OCP, OCS/ODF, ACM, Ansible, Docker) with teaching pedigree—having delivered instructor-led courses for Docker, Mirantis, Red Hat and enterprise clients—which sharpens his ability to translate complex designs into operational runbooks. Sebastian has led large migrations, HA and DR implementations for clients across media, transport, finance and government, and works regularly with edge/network optimizations (SR‑IOV, DPDK, NUMA) for performance-sensitive deployments. Equally comfortable in AWS and on-prem stacks (ROSA, RHV, OpenStack), he is known for pragmatic automation, upgrade strategies and incident triage at scale. A background in documentation and training means he not only fixes systems but also leaves teams more self‑sufficient.
