Who Am I ?

About Me

I'm a passionate Android developer with over 7 years of experience building high-performance applications for the Android platform. Proficient in Android SDK, Kotlin, and modern tools like Android Studio and Gradle, I specialize in developing scalable, user-friendly apps using Jetpack libraries (LiveData, ViewModel, Navigation) and architecture components such as Room and WorkManager. My expertise extends to core Android concepts (Activities, Services, Broadcast Receivers) and using Kotlin Coroutines for efficient, asynchronous programming. I have experience integrating APIs (REST, SOAP), Firebase services (Authentication, FCM, Analytics), and payment gateways (PayPal, RazorPay, Paytm). I am also familiar with Android Smart TV development, ML-Kit SDK, and ExoPlayer for media handling. Having worked in Agile/Scrum environments, I follow best practices in coding, design patterns, and architecture (MVVM, MVC) to deliver robust, maintainable solutions. I’m passionate about staying ahead of mobile development trends and ensuring optimal user experiences across all Android devices.
