Over two months, this developer delivered a reusable customer churn prediction workflow and comprehensive documentation for the H6WU6R/DSA3101-Group-4 repository. They unified data preprocessing, feature engineering, and model training using Python, Pandas, and Scikit-learn, integrating SMOTE to address class imbalance and merging datasets for a consolidated churn view. The developer refactored the project structure, removing deprecated scripts and organizing code under Customer Retention Strategies to improve maintainability and deployment readiness. In April, they focused on detailed documentation, outlining reproducible data preparation steps and enhancing onboarding. Their work enabled scalable analytics, streamlined collaboration, and consistent machine learning workflows for customer retention.

Apr 1, 2025April 2025 Monthly Summary for H6WU6R/DSA3101-Group-4: Delivered a comprehensive Bank Customer Churn Dataset Documentation and Setup Guide. Primary focus was on documenting the end-to-end data preparation pipeline (data cleaning by dropping irrelevant columns, feature engineering (Income_bin), dataset merging, encoding of categorical variables, and SMOTE balancing) and enhancements to documentation structure, formatting, and navigation to support reproducible preparation for customer lifetime value prediction. No major code defects fixed this month; impact centered on developer onboarding, reproducibility, and readiness for scalable data pipelines. Business value: faster onboarding, consistent preprocessing for CLV models, and improved collaboration.

Mar 1, 2025In March 2025, delivered a reusable churn-prediction workflow for H6WU6R/DSA3101-Group-4 and reorganized repository structure to boost maintainability and deployment readiness. The work unified data preprocessing, model training (Logistic Regression, Random Forest, Gradient Boosting), and evaluation, with improved handling of imbalanced data via SMOTE and data merging for a single churn view. Deprecated scripts were removed and files reorganized under Customer Retention Strategies to streamline future development and analytics deployments. Business value: enables faster, data-driven retention decisions and scalable analytics for customer churn.
