§ 05 · Home lab

The same operating discipline at a smaller scale.

Capabilities

Everything I run at home is self-hosted, sits behind a single identity provider and a TLS-terminating edge, and is fully monitored. The discipline applied to a 150PB archive is applied here too: single sign-on, full observability, off-site replication, and documented runbooks.

  • Public services behind one identity provider and a TLS edge
  • Metrics and alerting across every host and service with Prometheus and Grafana
  • Off-site ZFS replication with tested recovery runbooks
  • A local-first AI inference stack: Ollama, LiteLLM, WhisperX, Qdrant
  • Private git with CI on self-hosted runners
  • Automation, documentation, and CRM on the same platform
