Architected a RAG chatbot pipeline with hybrid search (BM25 + ChromaDB/Sentence-Transformers) and cross-encoder reranking to the top 4 of 10–15 chunks, served by Llama 3.3 70B (Groq) with function-calling to eliminate hallucinated figures. Built an LLM-as-judge harness measuring 83.3% retrieval hit-rate via ablation testing on reranking depth. Clustered 26 logged queries via K-Means into 6 topic groups, surfacing 5 FAQ content gaps.
