Homelab
Infrastructure that runs itself.
Where the day job continues: a small lab run like production, patched, backed up and watched without me having to remember any of it.
Hardware
- Proxmox VEThe main node: virtual machines and Docker hosts
- Proxmox Backup ServerScheduled, deduplicated backups of every VM
- Raspberry PiAn independent watchdog, still on duty if the main node goes down
Automation & patching
Ansible playbooks run from Semaphore keep every machine updated and hardened, with a Proxmox snapshot taken first so any change can be rolled back.
- Ansible
- Semaphore
- Gitea
Observability
Checkmk and Pulse watch the hosts; Uptime Kuma on the Pi double-checks from outside the main node.
- Checkmk
- Pulse
- Uptime Kuma
Network & security
A reverse proxy with certificates that renew themselves, redundant DNS with ad blocking, and secrets and credentials kept in one place.
- Nginx Proxy Manager
- AdGuard Home ×3
- OpenBao
Services
Docker stacks deployed through Portainer and kept current by Watchtower, again with a snapshot before each update.

Tools I wrote for it
- ansible-linux Idempotent patching for the whole lab: upgrades, common hardening, Checkmk agents and plugins, Proxmox snapshots and redeploys where needed. Private repo
- kuma-importer Builds Uptime Kuma monitors from the sources of truth already there: a ping per host in the Ansible inventory, an HTTP check per proxied domain. Private repo
- semaphore-discord-bridge A small bridge that turns Semaphore task results into rich, colour-coded Discord embeds. Private repo

About
The person behind it.
- Kenan KasumovicBorn & raised in Switzerland
- Linux System AdministratorSince 2021, senior from this year
- FocusAnsible & automation
I was born and raised in Switzerland, and I've been a Linux system administrator since 2021 — senior since this year, though the reality is I grew up inside the very place I work today, so the senior part came naturally.
These days my main focus is the Ansible ecosystem and automation in general: if it happens twice, it should happen by itself. Outside of work I love exploring new places, keeping active, and eating genuinely good food — and I'm a proper automotive enthusiast, Formula 1 in particular.
