Contributed to the SpikyCherry/DSA3101_group9 repository by building a modular data processing and modeling pipeline focused on real-time segmentation workflows. Over two months, consolidated and standardized Jupyter notebooks, centralized preprocessing and model training modules, and migrated legacy code to a cleaner project structure. Enhanced data quality and model performance by integrating hierarchical clustering and adopting XGBoost as the primary model, while improving onboarding through updated documentation and repository hygiene. Leveraged Python, Pandas, and Scikit-learn for data cleaning, feature engineering, and visualization, enabling reproducible analytics and faster iteration. Addressed maintenance overhead by removing obsolete files and clarifying notebook lifecycle management.

Mar 1, 2025March 2025 focused on laying a robust foundation for real-time experimentation and future Qn5-based workflows. Key work included consolidating the notebook lifecycle for real-time segmentation by renaming and centralizing notebooks under A5_realtime_segmentation variants, followed by cleanup of obsolete files to avoid confusion. Initiated Qn5 project scaffolding, created a dedicated Qn5 directory, and migrated core modules (preprocess.py, train_model.py) with updated paths, enabling cleaner packaging and reproducibility. Performed initial Colab-based scaffolding and file uploads to accelerate onboarding. Additionally, removed legacy Qn5 references to prevent drift and maintain a clean codebase. These efforts reduce maintenance overhead, accelerate onboarding for new team members, and establish a modular structure for scalable experimentation and deployment.
