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.
