About this Gig

Stop guessing next quarter's demand. I build forecasting models to plan inventory, staffing and budgets, and I show you how accurate they are before you rely on them.


WHAT I DELIVER

- Time series models: ARIMA/SARIMA, ETS, Prophet, VAR

- Machine learning forecasts (XGBoost/LightGBM) with calendar, price and promotion features

- Back-tested accuracy (MAPE, RMSE) against a naive baseline

- Forecasts by product, store or region, with prediction intervals

- Clean code you can rerun on new data


WHY ME

- Former Senior Data Scientist in sales and demand forecasting (US AI company)

- Built retail scanner-data pipelines for European brewers

- Econometrician with 7+ years of experience; Upwork Top 3%, 120+ projects
