- Integrate image frameworks (Coil, Glide) and animation tools (Lottie, MotionLayout) for a polished UI experience.
- Handle cross-device communications using Bluetooth, NFC, Wi-Fi, and Android connectivity APIs.
- Utilize system and health APIs (Health Services, Sensor Framework, Fitness Data) for enterprise and consumer applications.
- Implement robust testing pipelines, including unit testing (JUnit, Mockito) and UI testing (Espresso).
- Setup and maintain CI/CD pipelines using GitHub Actions, Jenkins, or Bitrise for automated builds and deployments.
- Integrate applications with RESTful and GraphQL APIs, Firebase services, and backend cloud infrastructures.
- Manage data persistence using Room, Realm, or DataStore while adhering to modern storage security practices.
- Optimize app performance through profiling, caching, memory leak management, and strict adherence to performance benchmarks.
- Ensure secure app design using biometric authentication, encryption, and secure data handling standards.
- Maintain code quality with Ktlint, Detekt, and Dokka documentation standards.
