👋 Hello!
I’m Erik, a senior software engineer and design enthusiast living in Berlin. Welcome to my personal blog, where I write about:
- 🤖 AI Agents & Automation - Building with Hermes, tool use, and what AI can actually do
- 🐧 Raspberry Pi & Homelab - Headless setups, NVMe boot, always-on services
- 🚋 Berlin - Events, Trams, City Life
- 🇪🇸 Learning Spanish - Vocabulary, Grammar, Culture
I built a personal AI agent named Puck that runs on a Raspberry Pi in my living room. It watches the tram schedule, keeps my wall dashboard updated, and helps me write this blog.
