Hi, I'm Florian.
I build the systems that
run behind the scenes.

Infrastructure engineer with a deep bias toward self-hosting, automation, and keeping things minimal. I spend my time wiring up containers, writing deploy pipelines, and making sure nothing pages me at 3 AM.

See what I've been building
01 Toolkit
Docker

Compose stacks, multi-stage builds, private registries. Everything containerized, nothing installed "just on the host."

Linux

Debian-flavored. systemd units, cron, shell scripts, and the occasional kernel parameter tuning when things get interesting.

n8n

Workflow automation glue. Webhooks, API chaining, conditional logic — replacing fragile bash scripts one node at a time.

Automation

CI/CD pipelines, scheduled tasks, sync jobs, alerting hooks. If a human is doing it twice, it should be a script.

Self-Hosting

Vaultwarden, Gitea, monitoring stacks, media servers. Owning the infrastructure means owning the data.

Nginx

Reverse proxy configs, TLS termination, rate limiting, and the quiet satisfaction of a clean server block.

If you're working on something that needs solid infrastructure, reliable automation, or you just want to talk shop about self-hosting — I'd like to hear about it. I'm most responsive over email, but you can also find me on the platforms below.
