Homelab

Self-hosted Kubernetes cluster at home. Beelink SER5 with upgraded 64GB RAM, 2TB NVMe, and an external DAS with 2x4TB drives. Proxmox as hypervisor, running four VMs that form a k3s cluster: one master, three workers.

Full GitOps workflow. Manifests in Git, ArgoCD syncs automatically, all changes through pull requests.

What’s running

Media stack. Jellyfin, Jellyseerr, Radarr, Sonarr, Prowlarr, qBittorrent.
Services. Uptime Kuma, KitchenOwl, Calibre, and more.
Automation. n8n as the workflow engine. Telegram bot interactions (torrent searches, recipe lookups), KFC order optimization, alerting integrations.
Networking. Traefik, ExternalDNS with Cloudflare, Tailscale, Nubulus tunnel.
Monitoring. Kube-Prometheus-Stack with Prometheus and Grafana.

Home Assistant

Home Assistant OS running as a dedicated Proxmox VM. Automation beyond infrastructure, into everyday life.

Laundry notifications. Alerts when the washing machine finishes based on power consumption.
Commute optimization. Training a model to recommend when to leave home to avoid traffic.

And more! Every time I solve one thing, I find three more to automate.

Monitoring & bots

Named after characters from The Fairly OddParents, because every infrastructure needs its magic.

Wanda. Deterministic alerting bot. Predefined alerts from Prometheus straight to Telegram.
Cosmo. AI-powered agent built on Claude. Monitors the cluster, diagnoses issues, runs read-only inspections, and creates tickets. Operates via Telegram, CLI, and paseo.sh for autonomous agent sessions. Cosmo is multidisciplinary: beyond infrastructure, it handles fitness tracking, nutrition, and other areas, each with its own context window.

Custom keyboards

I build mechanical keyboards from scratch. Picking every component, lubing switches and stabilizers, tuning the sound profile.

My current rotation:

Office. Neo65, Gateron Oil Kings, PC plate, lubed Durock V2 stabilizers.
Gaming. Tofu60 Redux, BM60 PCB, HMX Macchiato switches, PC plate, lubed Durock V2 stabilizers.
