🙋🏼‍♂️ABOUT ME

Hi, I am Eike, a German Software Engineer since 2015. I like developing Apps with Flutter, creating Backends with Java Spring Boot or Supabase and constructing High-Availability IT-Infrastructure as DevOps- and Cloud-Engineer with Kubernetes and other reliable and secure technologies.
At home, I created a fully automated cloudless Environment with KNX Bussystem, openHAB, Home Assistant, Zigbee and other shenanigans. My Home Lab consists of multiple Servers, running Proxmox, Kubernetes, DNS-Server, NGINX Reverse Proxy, Grafana, Node-Red, TrueNAS, Nextcloud, Unifi and many more.
Have fun, exploring my portfolio
