The World Is a Distribution
Data Science & Fractional Head of Data
The world is
a distribution.
Point estimates lie. Averages mislead. The shape of uncertainty is where real understanding lives — and where competitive advantage hides.
Distributional thinking
applied to real decisions.
I combine public datasets — legislation, labour markets, health registries, EU open data — with Bayesian methods, changepoint models, and simulation to produce analyses that domain experts cannot replicate without data science skills.
Bayesian inference
Posterior distributions over parameters, not p-values. Uncertainty quantified, not hidden.
Open data synthesis
Semantic Finlex, Eurostat, StatFin, EurLex — combined in ways no single-discipline analyst can.
Forecasting & simulation
Monte Carlo, generative models, changepoint detection. Predictions with explicit confidence bounds.
Fractional leadership
SMEs get a senior data strategy partner without hiring a full-time CDO. One day a week, full expertise.
"A single number — an average, a headline figure, a point forecast — is not an answer. It is a question about which distribution produced it."
