My Work

E-Commerce customer segmentation

An end-to-end machine learning pipeline built in Python using a ~1 million row retail dataset. It combines RFM feature engineering and K-means clustering with an XGBoost model to identify high-value B2B/B2C customers. The results and SHAP-based model explainability are presented in an interactive Streamlit dashboard for non-technical stakeholders.
