- Asynchronous & Background Tasks : Implement efficient background processing using coroutines, WorkManager, and services for long-running or network-dependent operations.

- UI Development : Build adaptive, responsive, and accessible UIs using XML and Jetpack Compose, ensuring pixel-perfect implementation across devices and screen sizes.

- Networking & Data Handling : Integrate RESTful APIs using Retrofit/OkHttp, manage offline data persistence via Room or Realm, and implement intelligent caching mechanisms.

- Testing & Quality Assurance : Establish unit, integration, and UI testing using tools like JUnit, Espresso, and Mockito to ensure code reliability and maintainability.

- Security & Compliance : Enforce secure coding practices, manage API keys securely, implement encryption where needed, and ensure compliance with data privacy regulations.

- Performance Optimization : Analyze and enhance app performance, memory footprint, and battery consumption using profiling tools.

- Collaboration & Mentorship : Collaborate with cross-functional teams including designers, backend engineers, and QA, while mentoring junior developers in technical design and coding standards.

Technical Stack :

- Languages & Frameworks : Kotlin, Java, Jetpack Compose, XML

- Architectures : MVVM, MVP, MVI, Clean Architecture
