Project description: Built a mobile cross platform Application called "Technician App". The Technician App is a cross-platform mobile solution that provides field technicians with a clear overview of their assigned devices and service tasks. It offers access to technical information, fleet data, spare parts, training, and guided instructions, while enabling standardized service reporting and seamless interaction between cloud services and connected devices.
