   As a Senior Mobile Application Developer, I led the design and development of a multi-targeted hotel booking application at Hyatt, building shared core logic and dynamic UIs tailored to each client brand using Swift, SwiftUI, and Xcode- I architected VIPER-based room reservation flows, enabling scalable, testable booking and cancellation modules- The app featured a SwiftUI-powered loyalty dashboard with real-time updates via Combine and GraphQL, enhancing user engagement with tier-based rewards and benefits- I implemented secure user authentication through AWS Cognito, supporting social login, MFA, and biometric validation- For concierge services, I crafted smooth, interactive UI transitions using SwiftUI animations and UIKit integration- I integrated real-time in-app messaging with WebSockets for notifications like room readiness and service alerts, and used Combine to create responsive hotel search and filtering experiences- Offline functionality was ensured through SQLite-backed reservation caching, while XCTest and XCUITest maintained high test coverage for critical flows- I also incorporated Live Activities and Dynamic Island using ActivityKit and WidgetKit for real-time service tracking, and implemented app-wide dynamic theming to support brand-specific designs and light/dark modes- To ensure performance and reliability, I used Instruments for profiling and memory analysis, and automated CI/CD workflows via Fastlane and Bitbucket Pipelines- Additionally, I integrated jQuery Mobile through WebViews for hybrid content, interactive hotel maps with real-time positioning, and support SDKs with deep link routing for seamless issue resolution.
