Infrastructure from the Metal Up

I'm an OpenShift Infrastructure Baremetal Architect at Red Hat, based in Minneapolis. My work spans the full stack of infrastructure: from PXE booting bare metal servers to deploying and managing production OpenShift clusters.

I specialize in disconnected/air-gapped environments, storage architecture (ODF, CSI drivers, NooBaa), network configuration, and GitOps automation. I build tools and documentation that help teams deploy and operate complex infrastructure reliably.

When I'm not architecting clusters, I'm exploring LLM serving on consumer hardware and contributing to open source infrastructure tools.
