About the role

- - Integrate SwiftUI into UIKit screens and vice versa using UIHostingController.
- - Optimize view performance by controlling what triggers view re-evaluation.
- - Take part in refactors and code migrations, such as Storyboards/UIKit to SwiftUI.
- - Apply dependency injection to decouple components and make testing easier.
- - Implement local persistence and sync strategies for offline use.
- - Build asynchronous flows with async/await and critically review AI-generated code.
- - Work with product, design and QA, and take part in code reviews.
