Collected, cleaned, and structured large-scale transactional and cash-point datasets for analysis. Conducted time-series analysis to model ATM cash movement; detected seasonal patterns and trends. Applied statistical models and machine learning for demand forecasting; engineered features from transactional and seasonal cycles. Built and validated predictive models using Python (pandas, scikit-learn, statsmodels). Analyzed evaluation metrics (MAPE, RMSE, R^2) to refine forecasting accuracy. Collaborated with cross-functional teams to translate forecasts into business decisions.
