Building
Sextant
Generates typed Go for Kubernetes operators from declarative state machines. Invalid state transitions become compiler errors.
Cloudflare Operator
Annotate a service with a domain → operator creates tunnels, DNS records, zero trust rules.
OCI Model Cache
Kubernetes operator that caches HuggingFace models in OCI registries. Webhook intercepts pods, streams weights with zero disk I/O.
