I build AI agents and help organizations adopt them. M.Sc. at KIT Karlsruhe, 10 yrs engineering. Seeking AI strategy and digital transformation roles in Germany.
Building an AI Agent That Actually Works in Production
Most AI agent demos are impressive. Most AI agents in production are disappointing. I’ve been running Tree AI — a personal AI assistant — every day for over a year. Here’s what actually matters when you move from demo to production.
What Tree AI does
Tree AI is a multi-agent system that runs 24/7 on my server. It handles:
- Voice input via Whisper STT → AI response → voice output (TTS)
- Smart home control (lights, temperature, devices)
- Calendar and email management
- Market analysis and Telegram channel publishing
- Adaptive personas for different contexts
It’s not a side project or a toy. It’s the thing I use to manage my day.
Self-Hosting Everything on a €6/Month VPS — What I Run and Why
My entire personal cloud — AI bots, analytics, automation, this website — runs on a single Hetzner VPS. €6 per month. Here’s exactly what’s running and how I set it up.
What the €6 buys you
A Hetzner CX22 gives you 2 vCPUs, 4GB RAM, 40GB SSD, and 20TB bandwidth. Based in Germany, so GDPR-compliant by default. For a single developer running personal infrastructure, this is genuinely more than enough.
