David Ajzental

Data scientist & AI enthusiast.

I'm a Brazilian data scientist based in Breda, Netherlands, an economist by training who fell for data and never looked back. I currently work as a Business Data Scientist at FitForMe, a Dutch health startup, in the intersection of data science, data engineering,AI where I build customer-behaviour analysis and models and ship AI agents that hand colleagues back hours every week. I have interest AND experience in venture capital, football analytics, economics, and public policy. Playing and studying all kinds of sports, watching movies and series, R&B music is what I do to wind-down. I also enjoy reading literature classics.

A place to express my interests and show the work, not just list it. The projects below are where I think out loud with data; football is simply the dataset I have the most fun with.

  Separating results from underlying performance across the three head coaches that led the SPFC's squad in the 2026 season — an expected-goals and expected-points model, benchmarked against all 20 clubs, that shows what actually changed in the football results.
