GitOps everywhere, Kubernetes at scale, and a stubborn refusal to click buttons twice.

Read-only cluster inspection as a kubectl plugin. One dispatcher, ~25 shortcuts, shipped through my own krew index. |
🏗️ kubearchPrometheus exporter reporting the CPU architectures every running image supports. Reads OCI manifests only, never pulls a layer. Built for arm64 migrations. |
