Experience
Data Science Intern
May 2025 — Present · Dallas, TX, US
Developed a video-based Retrieval-Augmented Generation (RAG) system for semantic search and real-time Q&A over Paycom training videos by processing Whisper transcripts with a custom chunking strategy. Integrated Milvus vector search and Llama3 to generate concise, timestamped answers with ~3s latency, enabling direct video jump to relevant segments.2. Implemented semantic-aware section classification to segment resumes by context, followed by named entity recognition (NER) using GLiNER to extract candidate information. Built an interactive dashboard to visualize key entities and section details, reducing manual review workload by 80% through batch processing.
