About me
I stabilize and modernize complex software platforms when systems become fragile, migrations stall, or delivery speed breaks down. My core focus is operating production-critical Kubernetes/OpenShift platforms: operating models, incident resilience, CI/CD under compliance constraints, and architectures that scale reliably. I take technical ownership, reduce uncertainty, and leave teams with systems they can run safely and efficiently.
Typical engagements
Rescue and stabilization of Kubernetes platforms in live operation, time-critical OpenShift migrations, CI/CD hardening for enterprise environments, and architecture reviews before large-scale rollouts.
