I'm software engineer with 4+ years of experience in Kubernetes-based storage systems. I'm maintainer and one of the top four contributors to the Rook-Ceph CNCF graduated project. I'm also maintainer of kubectl-rook-ceph. I have spoken at major conferences including KubeCon, Cephalocon, FOSDEM, and Ceph Days.
My work focuses on distributed storage, Kubernetes operators, and cloud-native infrastructure.

Session
Kubernetes has transformed how we run applications—but storage at scale remains one of its hardest challenges. Rook, a CNCF Graduated project, brings Ceph's battle-tested storage engine into the cloud-native world, delivering Block, File, and Object storage as a fully self-managed Kubernetes-native experience.
This talk uncovers the real-world truths behind running Rook-Ceph in production: what actually works, and the patterns that make enterprise storage reliable inside Kubernetes. We'll explore fast, repeatable cluster bring-up, proven Day-2 operational tactics, multi-tenant and isolation models, and strategies to survive failures, upgrades, and disaster scenarios.
You'll also get insights directly from upstream maintainers—covering lessons learned, common pitfalls, and how the community is shaping the next generation of cloud-native storage.
If you're evaluating, operating, or scaling stateful workloads on Kubernetes, this session will give you the clarity and confidence to run Rook-Ceph like a pro.
