Developed and maintained an end-to-end customer recommendation pipeline for the H6WU6R/DSA3101-Group-4 repository, focusing on data quality, security, and reproducibility. Built features for data cleaning, imputation, label construction, and model training using Python, Pandas, and Scikit-learn, producing per-user recommendations and output datasets. Enhanced project infrastructure by restructuring directories, updating dependencies, and improving documentation for data discoverability. Introduced encryption and decryption utilities with Bash and Docker to ensure secure data handling. Regularly removed obsolete data artifacts and refined data processing scripts, resulting in higher data integrity, streamlined machine learning workflows, and a maintainable, scalable codebase ready for ongoing development.
