I need a mobile app for both iOS and Android that allows customers to: - Make reservations for parking (departure and arrival) - Make workshop appointments - View and sign quotes and invoices The app should require user authentication via email/password. Additionally, it should ideally be connected to our workshop's web-based software. Ideal skills and experience: - Mobile app development for iOS and Android - Experience with user authentication systems - Backend integration with web-based software - Familiarity with UI/UX design for a seamless user experience
