    Supply Chain Risk Analytics

    Built an end-to-end supply chain risk analytics solution on a SQLite star-schema data model, engineering dual XGBoost classification models to flag at-risk shipments and suppliers. Applied SHAP explainability to surface the key drivers behind each risk prediction. Delivered a 5-page Power BI dashboard and published the complete project (code, models, dashboard) to GitHub and Power BI Service with a recruiter-facing README.
