Developed an end-to-end churn analytics stack for the SpikyCherry/DSA3101_group9 repository, focusing on scalable data pipelines, robust model training, and interpretable insights. Leveraged Python, Pandas, and XGBoost to implement data cleaning, preprocessing, and categorical encoding, followed by model training and evaluation. Integrated SHAP-based model interpretation to provide clear explanations of churn drivers, supporting business decision-making. Enhanced project documentation with a comprehensive data dictionary and improved repository hygiene by standardizing artifact management and updating .gitignore rules. Emphasized reproducibility and safe experimentation through organized notebooks and lifecycle management, enabling efficient deployment and transparent communication of machine learning results to stakeholders.
