PROFILE
Samuel Ngai
Samuel Ngai developed backend features for the NautiChat-SENG499-Capstone/NautiChat-Backend repository, focusing on scalable data preprocessing and automated data ingestion pipelines. He implemented a Python-based scalar data processing module that normalizes and summarizes sensor data for analytics, emphasizing modularity and thorough documentation. Samuel also engineered a daily vector database ingestion pipeline using APScheduler, integrating ONC OCEANS 3.0 API data and supporting dynamic environment configuration. His work included enhancing LLM retrieval-augmented generation with prompt engineering and QA feedback loops, improving data quality and model responses. The solutions demonstrated depth in API integration, data engineering, and robust backend development practices.
