About

I’m Stefanos. Nomad, photographer, videographer — and someone who has been refusing to lose data since 1995.

I run a homelab on three Lenovo M910q mini PCs in Prague. The cluster runs K3s with GitOps, Longhorn storage, and everything self-hosted. No Google, no iCloud, no subscriptions.

Beyond infrastructure, I build self-hosted automations — connecting services, eliminating manual work, making data do things automatically. On-prem AI is the current frontier: running Ollama, Whisper, and local models entirely on my own hardware, no cloud APIs, no data leaving the building.

This is my business card. If you want to understand what I do — read the posts.

Infrastructure: K3s · ArgoCD · Longhorn · cert-manager · Cloudflare Tunnel · SOPS+Age · Prometheus + Grafana

Automations: n8n · self-hosted workflows · on-prem AI (Ollama + Whisper via ROCm)
