Problem

Manual customer support required time to locate answers in product and support documentation.

My Role

Built the customer-facing RAG chatbot within a five-person team developing order and support systems.

Solution

Connected an LLM to approved product and support documentation through hybrid search and retrieval-augmented generation.

Architecture
