Project showcase

Selected systems,
in production.

Projects are most interesting after launch: when real users, operations, security, and recovery all become part of the design.

Home infrastructureOngoing

A small private cloud that stays understandable.

Proxmox workloads on a UGREEN NAS, ZFS-backed storage, private service networks, Pi-hole DNS, Tailscale remote access, hardware health reporting, monitoring, and off-pool backups.

  • ZFS
  • LXC
  • Tailscale
  • Pi-hole
03
sieglinger.netLive

A personal site with a deliberately short request path.

A compiled Bun server running in an unprivileged LXC on the home NAS. Cloudflare Tunnel is the only Internet path; the public pages need no database, client framework, cookies, or third-party analytics.

  • Bun
  • TypeScript
  • Cloudflare Tunnel
  • systemd
