- Build the server-driven UI (SDUI) rendering library behind 50+ live screens in the Zara app (carousels, marketing pages, catalog views) that teams update the same day, not on the weekly release train.
- Build the dynamic forms library that lets brand apps render different form configurations, such as those required by local regulations, without a redeploy.
- Write and review the public SDK API specifications consumed by four feature teams and by other SDKs that embed the library.
- Integrate the libraries with A/B testing and feature-flag systems for engagement experiments and remote UI configuration.
- Cover components with unit, UI, and snapshot tests across device sizes, orientations, light and dark mode, Dynamic Type, and RTL layouts.
- Develop components in an isolated sandbox with demo apps showcasing library usage; repo-level Copilot configuration holds agent-written changes to the same test and review standards.
