## About

I am a senior Android developer with 5 years of experience in product\-based startups\. I always look for a challenging yet supportive environment to contribute and grow as a developer\. Skills: Java, Kotlin, Jetpack Compose, RESTful APIs, RxJava, Coroutines, Flow, Unit testing, Git, Design patterns \(MVC, MVP, MVVM\), Android Material Design, Firebase, FCM, Hilt, Android SDK, Android Studio, CI/CD, Retrofit, App Profiling, Memory Leak Detection, App Size Optimization, ProGuard Some of my latest achievements at Crafto\(100M\+ Downloads\): Decreased the ANR rate from 1\.59% to 0\.65% for 3 million daily active users\. I achieved this by using the Android Studio Profiler, developing a custom threading mechanism to capture ANRs, and logging them to Firebase and Amplitude\. Reduced slow cold start rate from 23\.56% to 8\.91% by using app startup library and lazy initialization of components\. Reduced excessive slow frame rate from 3\.04% to 2\.30% by inflating layouts asynchronously and simplifying the nested XML structure\.
