About
I work in software development and tech for about 30 years. Most of the time I was self-employed and running my own software company. My focus was always on web and cloud technologies, data infrastructures, user experience, and security. In the recent years I expanded my interests and skills into artificial intelligence (neural nets, machine learning), and into several sustainability topics. I'm especially interested in using technologies as a major enabler for a more just, peaceful, curious, intelligent, and sustainable society.
I'm open for per-project hires, co-founding startups, or experimental collaborations. You can contact me via email or follow me on social media.

Recent Work
Computational Life Reactor (CLR)
CLR is an interactive browser implementation of the computational-life experiments studied by Agüera y Arcas and collaborators (mlst/YouTube). Random byte tapes are repeatedly paired and executed in the BFF language, allowing self-replicating programs to emerge without a fitness function or explicit selection process. CLR provides live population visualizations, frequency and compression measurements, and a step-by-step execution sampler. The simulation runs locally using WebAssembly and parallel browser workers. A great 12 minutes introduction into the topic featuring CLR is provided by Johannes Martin (Number Cruncher) on YouTube.

Climate Change Tracker is a public climate data platform that makes global and national climate change data clear, accessible, and up to date. It transforms complex scientific information into dashboards, charts, and insights that help a broad audience understand where the world stands on climate change. Launched in 2021 by Alex Borger and Jiddu A. Broersma, the platform is today operated by the non-profit Data for Action Foundation and reaches around 10,000 users per month.

Dashgrid is a realtime data tracking platform that turns raw data streams into clean, shareable dashboards. Data is pushed through a minimal API and appears live in beautifully consistent, responsive dashboards, and widgets. Unlike heavyweight BI and data exploration tools, Dashgrid is built around simplicity: curated signals over noise, made for the people tracking the numbers as much as the developers providing them. Dashgrid launched in Q1 2026 and is currently in open beta.
