Hey, I’m osifu

I learn by building, breaking, and repairing—then documenting the path so it’s repeatable.

What I’m building

A self-hosted platform that feels like production:
- MicroK8s cluster across 3 Intel NUCs, 2× RPi 4, 2× RPi 5
- GitLab CE on an iMac (2015) behind Cloudflare Tunnel
- OpenTofu + Packer for immutable hosts; ArgoCD/Flux for GitOps
- Observability with Prometheus/Grafana/Loki, Runtime security with Falco
- Core apps: Home Assistant, Pi-hole, Jellyfin/media stack
- Experiments with open-source LLMs as local copilots

How this site ships

Astro + Tailwind v4 (via @tailwindcss/vite)
Built with pnpm in GitLab CI
Deployed to Cloudflare Workers (Static Assets) with Wrangler
Branch model: develop → staging.osifu.me, main → osifu.me

Principles I work by

Computers should belong to people. I favor tech that returns control to the user—no dark patterns, no lock-in.
Fight centralization. I build and fund things that frustrate platform consolidation; self-hosting first, federation when possible.
User sovereignty. Prefer designs where I can self-manage my own services and data (“sovereign cloud” mindset).
Sustainable open source. Good software should be open to scrutiny and tinkering—and creators should be able to make a living.
Privacy with integrity. Respect users by minimizing data collection and being transparent if any telemetry exists.
Realism about big tech. Oligopolies form; I design for portability so switching costs stay low.

Repair as practice

Perseverance: Small steps, repeated daily, redraw the map.
Kintsugi mindset: Cracks aren’t flaws—they’re the story of repair.
Gratitude: Notice, name, and keep what is good.
Tinkering > Theory: Ship, measure, improve.
