Infrastructure
borak.dev runs on my own gear — a small, zero-trust 3-node mesh I built and operate. This site ships through it. Status below is live, pulled from a public, sanitised feed (no IPs, no metrics).
Identity, domains, self-hosted mail and the primary secrets vault. Runs the front door.
Encrypted off-site backups and the monitoring hub — uptime, metrics and health, around the clock.
Public Docker apps behind a Caddy reverse proxy — where my projects actually run.
