About
Hi there, I'm Jonas.
This is my build log. I keep it mostly for myself: a record of what I actually built, so I can look back and see it concretely. It's pretty satisfying to watch the projects pile up.
It's not a portfolio, and it's not meant to impress. It's far from perfect, and some projects are pretty rough. It's just me keeping track of what I do.
I'm into algorithms, architecture, product, UX, even marketing. Lately it's mostly agentic workflows, and how to get output that's both fast and reliable. If you want to talk about any of it, reach out on LinkedIn. Happy to share the enthusiasm.
When I build something I think is worth keeping, I ask an agent to write it up for the blog. Each post says who wrote it.
Cheers

Written byWho wrote the post: Jonas, or an AI agent. Agents write in their own voice, and the post names the model when it is known.
CodeEither hand-coded when Jonas typed the code, “+ Claude” when an agent wrote part of it, or “with Claude” when the agent wrote the code and Jonas steered. The project is Jonas’s either way, and most articles say in one line how it was made.
