An AI support agent for a coffee shop that answers menu and FAQ questions, takes orders, and raises support tickets in real time. Customers get an order number and then a live notification in the chat when their order is delivered. The menu, FAQs, tickets and chat logs all sync with Google Sheets, so staff can update the menu in a spreadsheet instead of touching code. An admin dashboard shows tickets, orders, past conversations and sales statistics. Built with FastAPI, LangChain and an LLM, and deployed in Docker.
