I used FAISS as the vector database with a hybrid search strategy — combining dense embeddings from GPT-4 with keyword-based retrieval to improve recall. I implemented intelligent chunking with overlap and preserved document metadata so the model knew exactly which source each chunk came from. This was critical for traceability and compliance

I implemented a hybrid retrieval strategy — combining dense embeddings from OpenAI's text-embedding-3 model with sparse keyword-based retrieval using BM25. This ensured I captured both semantic meaning and exact term matches
