Casey writes.

This is the writing of Casey Romkes, an independent technologist in Brandenburg, near Berlin: a growing archive of essays, reflections, and field notes on AI adoption, technology, leadership, and the craft of building. Pieces run in English, with a few in Dutch and German, and include the recurring newsletter The Brief Pause. They are set chronologically, with no algorithm deciding what you see.
