I need a pair of fully-featured productivity apps, one native for iOS in Swift and one native for Android in Kotlin. Both will connect to an Angular front-end portal backed by Spring Boot and PostgreSQL. Core workflow The apps must let users create and manage tasks, see a unified calendar, and run a lightweight time-tracking timer. In addition, users should be able to scan documents or barcodes with the device camera, automatically extract the image data, and update on-hand inventory in real time. Systems & integrations The mobile clients and the Spring Boot API have to exchange data securely with our SAP instance for user accounts, project codes, and stock levels. I may expand later to services such as Google Workspace or Microsoft 365, but SAP connectivity is the must-have for this phase. Acceptance criteria • Swift and Kotlin source that builds cleanly in Xcode and Android Studio • Angular admin portal served by Spring Boot with JWT-based auth • PostgreSQL schema and migration scripts • Working SAP integration (create, read, update inventory and task objects) • Unit and basic UI tests for all critical flows • Deployment guides for App Store, Google Play, and the backend If the scope is clear and the toolchain matches your expertise, I’m ready to move quickly.
