Purav Parab contributed to the DrAlzahraniProjects/csusb_fall2024_cse6550_team3 repository by engineering a robust retrieval-augmented generation (RAG) system with enhanced document filtering, answerability tracking, and evaluation metrics. He improved both backend and frontend components using Python and Streamlit, refining the user interface and implementing advanced data validation and visualization. His work included prompt engineering for large language models, integration of FAISS for vector search, and expanded test coverage to ensure reliability. By addressing unanswerable question handling and refining feedback mechanisms, Purav delivered a more accurate, resilient, and user-friendly chatbot platform, demonstrating depth in natural language processing and system design.
