iStore – AI Agent & Full Stack

iStore is a full-stack e-commerce application integrated with an AI agent that enables conversational shopping. Users can interact with the system using natural language to browse products, manage wishlists, and complete purchases. The backend is powered by FastAPI, with a LangChain-based agent orchestrating intelligent user interactions, and the system is containerized using Docker for deployment.
