-    <h1>Hey, I'm Stefan Koelle 👋</h1>

     <p>Welcome to moonweb, my personal corner on the internet. This is where I document my homelab, smart home setups, infrastructure experiments, retro hardware, and the code that ties it all together.</p>
     <p>I'm a Senior Software Developer &amp; Architect based in Munich with 20+ years in the trenches, from Turbo Pascal on the 486 to .NET Core, 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 in the day to today's Proxmox cluster. Have a look around.</p>

   <h2>What this site is about</h2>
-  <p>moonweb is the personal project site of Stefan Koelle, a collection of projects that have grown over the past 25 years. What started as a single 486 running a BBS in the mid-90s has turned into a full homelab with Proxmox, Docker, smart home automation, and a growing collection of retro hardware. The name "moonweb" comes from the original domain moonweb.org, which has been online since 2000.</p>

The name "moonweb" comes from the original domain moonweb.org, which has been online since 2000.</p>
   <p>Each section of this site documents a different part of the setup. The <a href="/infra/">infrastructure section</a> covers the Proxmox cluster, Synology NAS, Docker containers, networking, and backup strategies. The <a href="/smarthome/">smart home section</a> shows what automation projects are running, from Tasmota energy monitoring to MQTT sensors and AirPlay audio. The <a href="/code/">code section</a> lists the public GitHub projects that power these setups, and the <a href="/retro/">retro section</a> documents the hardware collection.</p>
