Cusco → the Netherlands → London / Oxford
where the work comes fromEvery open binary market on Polymarket, Kalshi and Manifold — thousands of questions about elections, wars, AI, rates, weather, the end of the world — fetched, embedded by meaning, and drawn as a navigable galaxy.
A small artificial stock market in the browser: a real limit order book with price-time priority, five kinds of trader, a hidden true value the price is supposed to find — and buttons to sabotage all of it.
A career mode that starts at sixteen in the last division of the country you choose and ends, if you last, with you managing from the dugout — with everything those games leave out.

data science · 2026
I grew up in Cusco and moved to the Netherlands to study law — until I started building GPT pipelines to help write my essays, before ChatGPT existed. That was the end of law. I did the Le Wagon data science bootcamp, then launched AICOS, an AI customer-service tool for hotels in Peru that signed its first paying clients. Back in the Netherlands I won a hackathon with an ADHD reading extension, enrolled in ICT at Fontys, and kept shipping on the side.
The projects share a rule: if a claim can be tested, it runs as a test. Combinada Lab asserts that a backtest cannot see the future. The market simulator reproduces a 1993 economics paper in eighteen assertions. DataSubjects agreed its kill criteria before the first experiment ran. I would rather show you a model working than a slide about one.
Outside of code: tennis, jiu jitsu, hiking, and thinking about wine — the growing and making of it. Jiu jitsu makes sense to me as a modeller: real-time problem solving with incomplete information, and the mat does not care what you believed.
