Diagnose and resolve mobile performance bottlenecks including:

App startup time, FPS drops, memory leaks

Heating issues, over-rendering, and expensive widget rebuilds

Battery optimization, efficient network calls, caching strategy

Run in-depth profiling using tools like Dart DevTools, Android Profiler, and Xcode Instruments

• OTT-Specific Engineering

Optimize video playback workflows for low-latency streaming

Implement efficient background processes for downloads, DRM, content sync, and push notifications

• Product & User Experience Ownership

Collaborate closely with Product, Backend, and Video Engineering teams

Convert business/product requirements into high-performance technical solutions

Ensure UI/UX consistency across platforms while maintaining performance budgets

• Code Quality & Leadership

Write clean, extensible, and maintainable code with strong adherence to SOLID and reactive programming principles

Review code for mid-level and junior engineers; act as a mentor across teams
