- Designed and implemented end-to-end user onboarding and authentication flow, including input validation, API handling, and error states - Built a dynamic profile settings screen with edit, save, and real-time sync features using MVVM - Developed complex UI layouts using Jetpack Compose, enabling faster prototyping and reducing boilerplate code by 40% - Ensured UI responsiveness across screen sizes and supported dark/light themes using Material Design 3 guidelines - Integrated RESTful APIs using Retrofit and managed data states via ViewModel + LiveData / StateFlow - Implemented offline data caching using Room with auto-sync functionality when network is available - Used DataStore for key-value persistence to replace SharedPreferences in user settings management - Managed concurrency and long-running tasks with Kotlin Coroutines, improving app responsiveness - Used Flow to observe and react to data changes in real time across UI components - Built UI tests using Espresso and Compose UI Test to ensure regression-free releases - Integrated Firebase Crashlytics to monitor crashes and reduce ANRs by identifying performance bottlenecks - Configured GitHub Actions pipeline to automate build, test, and release stages - Reviewed merge requests, provided feedback, and contributed to maintaining coding standards

• Developed production-grade Android applications using Kotlin, Jetpack Compose, and MVVM architecture for a 30% performance improvement • Collaborated in Agile environment to deliver new features on bi-weekly sprints • Migrated legacy XML-based UI components to Jetpack Compose, reducing UI development time by 40%

- Reduced app crash rate by 40% within 2 months after stabilizing key features and fixing memory leaks - Helped increase monthly active users by 25% after launching a redesigned onboarding flow and feature walkthrough - Identified and resolved memory leaks and performance bottlenecks using Android Profiler, reducing app ANRs by over 40%. - Optimized RecyclerView rendering logic and introduced pagination using Paging3, leading to a 60% smoother scroll on lower-end devices. - Reduced cold start time by implementing lightweight splash screen strategy and deferring non-critical initializations.

- Built responsive user interfaces using Jetpack Compose and XML layouts, following Material Design principles - Implemented MVVM architecture with LiveData, ViewModel, and Room for clean data flow and persistence - Integrated REST APIs using Retrofit and parsed JSON responses for displaying dynamic content - Used Coroutines for asynchronous operations such as network requests and local database queries - Wrote basic unit tests using JUnit and created UI tests using Espresso for critical app flows - Used Logcat, Crashlytics, and Android Profiler for basic performance analysis and crash debugging - Participated in daily standups, sprint planning, and retrospectives as part of an Agile/Scrum team. - Worked with Git and GitLab for version control, branching, and code reviews. - Collaborated closely with UI/UX designers and backend developers to align on feature requirements and API contracts. - Attended internal knowledge-sharing sessions on topics like dependency injection, design patterns, and Jetpack libraries.
