     <p>I'm a Senior Software Developer &amp; Architect based in Munich with 20+ years in the trenches, from Turbo Pascal on a real 486 back in the day to .NET, Kubernetes, and AI-driven development today. By day I build microservices and cloud architecture, by night I dive into smart home automation, restore retro computers, and automate things that don't necessarily need automating.</p>
     <p>Everything here runs on a homelab that has been evolving since the mid-90s, from multiple 486s and Pentiums back then to today's Proxmox cluster. Have a look around.</p>
