Yaga.sh
My experimentation platform. Where I experiment and build things.
- Agents, small AI tools and black boxes you can argue with.
- Miss Yaga is its conscience. She has opinions about your model.

I build AI people can check. Forecasts, agents and decision tools that people actually trust and use.
Heineken spends about €7.9 million on marketing and sales a day. Someone decides where every one of those euros goes. The models were ready early. The people deciding still trusted their spreadsheets more.

Then the measured lift decides next year’s budget.
The first hire at a Chinese architecture firm’s Polish office, set up in Poland from zero. One of two co-founders of MAD Architects’ computational design group in Beijing. The first product person in Heineken’s Global Analytics & AI Hub. Each time, the hard part wasn’t building the thing. It was getting people to use it.
Worked at and built for
I trained as an architect and wrote the parametric tools behind double-curved facades in Beijing. I spent eight years in China. Based in Guizhou as the client-facing lead, I brought in a ~70M RMB residential project in Mandarin, with a design team in Poland behind me. Now I build with AI agents, hands-on, every day. Product is where the three meet: I can shape what people see, earn the trust of the people who will use it, and build the first version myself.
I build with Claude Code and AI agents. Spec first: I write the spec, coding agents build, and I review every change. One rule across everything: the model reads and summarises, deterministic code decides.

Miss Yaga says
“Three hundred years I read tea leaves. Now they call it a confidence interval.”
Eight years working in China, back and forth ever since. I wrote the scripts behind a facade and an opera house interior at MAD, and competition wins at AREP. A decade before “AI agent” was a phrase, I was building evolutionary solvers that bred building geometry from a fitness function.

Optimal was easy. Buildable was the job.
Tell me what it predicts and who ignores it. I’ll tell you what I’d build first.
