Debug issues using ADB, Logcat, and LeakCanary to identify and resolve crashes or ANRs.
Performance Optimization
Profile and diagnose performance bottlenecks (e.g., UI jank, memory leaks, high CPU usage) using Android Studio tools (CPU Profiler, Memory Profiler, Systrace).
Optimize app startup time, UI rendering (Jetpack Compose or View-based), and resource-intensive operations (e.g., image loading, database queries, network calls).
Reduce battery consumption and memory footprint for a seamless user experience.
Concurrency Management
Refactor asynchronous code to use Kotlin Coroutines with proper scopes (viewModelScope, lifecycleScope) and dispatchers (Dispatchers.IO, Dispatchers.Default).
Fix concurrency issues such as race conditions, deadlocks, and improper task cancellation.
Replace deprecated threading mechanisms (e.g., AsyncTask) with modern solutions like WorkManager or coroutines.
Android Compatibility
Ensure compatibility across Android API levels 30 (Android 11) to 35 (Android 15), including Google Pixel-specific optimizations (e.g., Tensor chip support).
Implement backward compatibility using Compat libraries (e.g., ActivityCompat, ContextCompat) and feature toggles.
Handle Android 15-specific changes, such as predictive back gestures, biometric updates, and foreground service restrictions.
Play Store Deployment
Resolve dependency conflicts and update libraries (e.g., Jetpack, Firebase, Google Play Services) to stable, compatible versions.
Set up beta testing tracks and staged rollouts for pre-release validation.
Codebase Maintenance
Audit and refactor legacy Java/Kotlin code for maintainability and performance, leveraging Kotlin 2.2.0 features (e.g., K2 compiler, sealed interfaces).
Optimize Gradle build configurations to reduce build times and resolve dependency conflicts.

Prior work on apps targeting Google Pixel devices (e.g., Pixel 9, Pixel Fold).
Knowledge of Android 15-specific features and Play Store policy updates.
Project Details
Duration: 4–6 weeks (depending on app complexity).
Location: Remote, with regular check-ins via Slack/Jira.
Deliverables
Optimized codebase with resolved performance and concurrency issues.
Comprehensive test suite covering critical flows and edge cases.
Play Store-ready App Bundle (.aab) and deployment documentation.
Performance benchmark reports showing improvements (e.g., reduced latency, memory usage).
Timeline
Week 1–1: Code audit and performance profiling.
Week 2–4: Refactor code, fix concurrency issues, and optimize performance.
Week 4–5: Compatibility testing, Play Store preparation, and final validation.
