A full-stack web application for managing a sweet shop's operations - built as a personal learning project to deepen understanding of role-based access control, JWT authentication, and full-stack development with the MERN stack. The system serves three user roles (Admin, Staff, Customer) with cleanly separated feature sets: Admin oversees all accounts and data but cannot place orders, Staff manages inventory and sweets data, and Customers browse, purchase, and track their payment history.
