At Tata Consultancy Services, I developed and deployed enterprise Generative AI chatbots using Python, LangChain, Azure OpenAI, and hybrid RAG architecture. They support 500+ daily user queries.
I built document pipelines using OCR, semantic chunking, SBERT embeddings, and FAISS to process 10,000+ enterprise documents. I also designed LangGraph workflows that reduced deployment iteration time by 40%.
I implemented RAGAS evaluation, achieving 80% response accuracy and reducing hallucinations by 35%. I also used LangSmith to monitor responses, retrieval quality, latency, and token consumption.
