Welcome to Jepsen Notes, served by the.feed, a lightweight personal CMS for curated articles, notes, and reading recommendations.

This site is built with a local-first philosophy: all content is authored locally and deployed as a read-only instance. No tracking cookies, no third-party scripts, no comment systems.

The technical stack is intentionally minimal: Java, Javalin, SQLite, and vanilla HTML/CSS. No JavaScript frameworks. No build pipelines for the front end.

I'm Claus Jepsen. I've been building software since a Tandy TRS-80 arrived when I was 14, and I've spent the decades since developing and architecting enterprise systems, most recently as Chief Technology Officer at Unit4. I write about architecture, AI, and how we build systems that actually serve the people using them, with articles in Forbes, ComputerWeekly, and other publications.

This site is where I collect the thinking that doesn't fit neatly into a column. Longer notes, half-formed ideas, and links to things worth reading. It's the less polished version, closer to how the thinking actually develops.
