I want to understand how things work.

The money side and the physical side: how a thing is actually made, moved and kept running. I have never managed to stay inside one subject.

About

Show me anything and I want to follow it down. An AI model runs on GPUs, the GPUs come out of a chip plant, the plant runs on what a mine digs up. I want the whole chain, and I want to know who does the work at each step.

That has dragged me through law, physics, economics and history without letting me settle in any of them. I trained as a lawyer, then left for Germany to study physics because I wanted to reach general relativity. The math was harder than I was. I am still at it.

Until I was about twenty-five I thought history had nothing to teach anyone. Then a few strategy games showed me economies as systems with moving parts, and I never got back out. It turned into a novel: 2,400 people from present-day Shanghai land in southern Africa in 1628 and try to build a country. I wanted to know what that would really take, down to who makes the toilet paper. The first twelve days ran to close to a million words, and the world underneath them is now a model that refuses to compute when the world I describe is impossible.

I learn a subject by building something about it. Economics became an interactive textbook, walkthroughs of the questions economists still argue about, timelines and atlases. That is Uniflection.

For a living I build and run businesses. I spent seven years running a trading and sand-dredging company on the ground in Cameroon, from nothing to about fifty people. Then hardware brands in Shenzhen, other people's and a consultancy of my own. Since 2026, a consumer AI company with an old friend. What I took from all of it is that knowing what to do is the small part. Getting it done, with the people and the machines you actually have, is where the difficulty lives.

For about ten years I tried to learn programming and it never stuck. In 2025 AI started writing the code, and it finally did. Agents now do the operating work under everything above, this page included.

Notes

What building these things taught me, across all of them rather than inside any one. A simulation that refuses to compute an impossible world, and what that says about planning. Douala, and the distance between a plan and a finished job.

The first one is being written.

To get them by email, write to me with “Notes” in the subject.

Things I've made

Each of these has its own home, its own readers and its own way of telling you when there is something new. This page is only about me.

1628 South Africa
The novel, in English and Chinese, and the world underneath it: the colony's daily state, the possibility space it was solved out of, and a map of how the whole machine is operated.
Uniflection
Walkthroughs of big, contested questions, interactive books and atlases, in four languages.
STERN Trading & Ingeniering Services
STIS, the company in Cameroon: sand dredging, earthworks, civil works, equipment and trade. Co-founded in 2011 and still ours.
Latent Spacex
The consumer AI company, in Singapore. I joined as a partner in 2026.
