What I'm looking for

I am looking for a senior Red Hat/cloud infrastructure role where I can lead migrations, build automated, secure, highly available platforms, mentor teams, and drive operational excellence.

I am a Red Hat certified architect with extensive experience designing, migrating and operating large-scale Linux and private cloud platforms, including OpenShift, OpenStack and Ceph. I bring a proven track record of leading migrations, automation with Ansible, and delivering highly available infrastructure for enterprise clients.

Across roles I have designed and implemented bare-metal OpenShift offers, managed private cloud platforms, automated builds and migrations (over 1,000 servers), and handed over robust solutions to support teams. I focus on performance tuning, security hardening and operational runbooks to ensure maintainability.

I value clear documentation, knowledge transfer and collaborative leadership, and I seek opportunities where I can apply deep Red Hat and cloud expertise to solve complex infrastructure challenges and mentor teams.
