Overview
This service turns finished designs into working screens and reusable components inside a new or existing mobile codebase, including layouts for different screen sizes, loading, empty and error states, animations and basic accessibility. Business logic and backend work are outside this service unless added separately. The client receives implemented screens in their repository, a component set matching the design system and notes on any deviations from the mockups.

Service FAQ
The service covers the user interface layer. Screens can use placeholder data or be connected to existing APIs if that is part of the agreed work, while building backend logic is a separate service.
