Worked on Skyscanner/backpack-ios, delivering features and fixes that enhanced UI consistency, accessibility, and developer experience across the iOS codebase. Built and standardized components such as hotel star ratings and map markers, introduced snapshot testing infrastructure for automated UI regression checks, and improved interaction reliability in SwiftUI controls. Addressed localization and accessibility by refining RTL behavior and hiding non-essential elements from screen readers. Leveraged Swift, SwiftUI, and Xcode build tools to implement robust UI updates, expand test coverage, and streamline build processes. Maintained clear commit hygiene and backward compatibility, ensuring stable releases and a maintainable, scalable design system for iOS.
