About me I like fiddling computer stuff, all kinds of science. Technologoy underpins most of our modern life so we should be able to understand it, not only consume it. So I run my own servers and services because I believe we should be more independent from big tech. This blog is where I write about what I build and what I learn. The focus is digital sovereignty, open infrastructure, and security. These are not abstract principles but operational realities.
I have spent more than 10 years in the public sector, which has given me a particular perspective on where digital infrastructure is heading and what it would take to build it differently. In addition to my ample experience in the public sector, I am currently expanding my skills by working through a Master Program in Computer Science, further building my skills and competencies in the field of digital sovereignty.
Other than that I do (all kinds of) sports, practice yoga, dance tango argentino, and travel when I can.
My Stack Three bare-metal Proxmox nodes in Germany, connected via an encrypted full-mesh VXLAN with pfSense as the gateway, somewhere north of thirty self-hosted services from cloud storage (nextcloud), photo management (ente), office backend (paperless-ngx), over a self-hosted LLM instance (ollama) to automation (n8n). All this is underpinned and protected by a SIEM stack (Wazuh, Suricata, Zeek). None of it is in someone else’s cloud - I own all of it.
