Developed three end-to-end data science features within the nikbearbrown/INFO_7390_Art_and_Science_of_Data repository, focusing on practical applications of AI and machine learning. Delivered a causal inference notebook suite for customer segmentation, leveraging Python and Jupyter Notebooks to analyze the TWINS dataset with statistical and visualization techniques. Built a few-shot learning workflow for large language models using LoRA, enabling parameter-efficient fine-tuning for sentiment analysis tasks. Designed and deployed a travel itinerary generation pipeline that integrates web scraping, AWS S3, Snowflake, and Pinecone embeddings, culminating in a backend with a chat interface and PDF output for automated itinerary delivery.
April 2025 — Key features delivered across nikbearbrown/INFO_7390_Art_and_Science_of_Data: 1) Causal Inference Notebook Suite for Customer Segmentation; 2) Few-shot Learning Notebook for Language Models with LoRA; 3) AI-Generated Travel Itinerary End-to-End Pipeline. These efforts deliver end-to-end data science capabilities: from data loading and causal analysis to parameter-efficient model fine-tuning and a production-like data pipeline with web scraping, embeddings, and a chat interface. Business value includes improved segmentation decision support, faster experimentation with LoRA-based fine-tuning that reduces compute, and scalable, automated itinerary generation.
