I’m an open-source developer with a long background in TYPO3
(maintainer of tt_news since 2004).
Recently, my focus has shifted toward AI-powered tools — and toward using AI as part of the development process itself.
I’m exploring how AI can help us build software that, in turn, uses AI to support humans in thinking, tracking, and decision-making. This includes what I like to call vibe coding: fast, iterative, curiosity-driven development with AI as a collaborator.
-
open recall
An experiment in AI-assisted knowledge recall — exploring how ideas, notes, and connections can be resurfaced at the right moment. -
rowing tracker
A lightweight rowing workout tracker, designed with simplicity in mind and room for AI-supported insights.
Both projects are built with AI and are about AI — not as a gimmick, but as a practical tool for solving real problems.
