Infrastructure and self-hosting
Proxmox, Talos Kubernetes, GitOps, mail, backups, PKI, MikroTik networking, Omada switching and wireless, observability, and the constant effort to keep everything understandable and recoverable.
Tools and workflows
Claude Code, worktree-heavy Git workflows, Zellij, Ghostty, code-server, Apple devices, and small pieces of automation that reduce friction or make a system easier to reason about.
Everything else
Fitness, motorsport, travel setup tinkering, and the occasional reverse-engineering or security investigation when an app or device deserves a closer look.
