Hi, I'm Andreas.

I build AI systems, web experiments and self-hosted infrastructure. Everything below runs on my own server.

02. About me

I'm Andreas, a developer and tinkerer from Denmark with a passion for artificial intelligence and self-hosting. I like understanding the whole stack — from the model generating an answer to the server delivering it.

When I'm not building AI chatbots, I'm experimenting with games, automation and whatever else my home server can be talked into running.

// currently: building RAG systems at AETHER.AI
