I'm looking for a simple Android app written in Kotlin that will help a service maintain order. A clean, uncomplicated interface is all I need. Workflow • Secure login using email/password with role-based access (administrator, technician). • Panel for adding or editing clients • Technicians add or select a client, and then add an installation or service. * List of devices for the next inspection by date (the technician enters the inspection after the installation or service) Technical Notes • Kotlin + the rest your suggestion • Keep the user interface simple Tasks 1. A complete Android Studio project with readable, well-commented Kotlin code. 2. An APK (or AAB) file ready for internal testing. 3. A setup guide covering the environment, build steps, and any external services used. I will test by logging in with both roles, creating clients and devices. Budget: 250 USD Please write directly in a private message.
