• Actively participating in release and sprint planning, artifact creation, sprint testing, regression testing, demonstrations, retrospectives, and solution releases.
• Analyzing complex mobile-related challenges (such as offline synchronization, local data encryption, battery optimization, and memory management) and creating innovative solutions.
• Ensuring mobile application quality and timeliness of work, resolving bugs, and providing periodic performance reports.
• Providing mentorship and code-review guidance to mid-level and junior members of the mobile team.

• Mobile streaming technologies (experience working with full-motion video, ExoPlayer, and interactive live data streaming on Android is highly desired).
• Object-Oriented Design and Functional Programming concepts.
• Managing asynchronous programming, multi-threading, and background processing (Kotlin Coroutines, Flow, or RxJava).
• Source code control systems and concurrent development workflows (Git/GitFlow preferred).
