Kiosk-Based Vehicle Management Application Development

I'm looking for a skilled software developer to create a kiosk-based application. This app should have distinct backend and frontend functionalities, designed for installation on Ubuntu OS kiosks. The application will serve two key user groups: office personnel who manage vehicle and towing fee data, and vehicle owners who need to retrieve and pay fees. Key Requirements: - A secure username/password-based login/logout functionality for different user roles: office personnel, vehicle owners, and administrators. - An interface for office personnel to input and manage vehicle data. - A user-friendly frontend for vehicle owners to access and pay towing fees. - Integration with a Pax A920 payment terminal for seamless transactions. The application should use an SQL database for managing vehicle and towing fee data. The ideal candidate should have: - Proven experience in developing kiosk-based applications. - Strong expertise in SQL database management. - Skills in creating secure user authentication systems. - Experience in integrating software with payment terminals. Looking forward to receiving your bids.
