SOTIPAPIER is a full-stack RFID system that tracks paper rolls (bobines) across a paper mill's warehouse in real time. The backend (Node.js, Express, Prisma, PostgreSQL, Socket.io) drives live roll tracking from RFID readers, delivery-order (BL) verification, quality holds and a grid-based warehouse map. A Next.js admin dashboard gives managers full control over inventory, orders and layout, while a Flutter mobile app equips forklift drivers with handheld and chariot-mounted scanning to locate, store and prepare rolls right on the floor.
