About

I’m Björn Roberg, a software developer based in Sweden. I spend my days building systems that have to work reliably, and my spare time wondering why they don’t. I write here to slow down my thinking — to examine ideas about technology, epistemology, and how we reason about complex things. If any of it is useful to you, great; if it starts a conversation, even better.

What I work on

My focus areas are AI agents, developer tooling, and software architecture. I build mostly in Python, TypeScript (and web stuff in general), Rust, dotnet/C♯, Go (and others) — picking whichever fits the problem. Most of what I write about here comes from building real systems and noticing patterns worth examining.

Open-source projects
