About

I'm a Software Engineer specializing in Android development, building scalable, high-performance mobile applications with Kotlin, Java, Jetpack Compose, and modern Android architecture components. Currently, I'm working as an Associate Software Engineer at Cricbuzz, where I develop and optimize features for high-traffic sports applications. My work includes redesigning live auction tracking systems, optimizing short-form video playback using AndroidX Media3 PreloadManager, building internal developer tools with Jetpack Compose, and improving network efficiency through Retrofit and Square Wire Protobuf. Previously, at DigiValet, I worked on Android applications and cross-platform solutions using Kotlin Multiplatform (KMP). I developed an automated UI Themes SDK using Kotlin Symbol Processing (KSP), integrated IoT functionality through MQTT and WebSockets, implemented secure authentication using AWS Cognito, and built real-time features for connected devices. Technical expertise: • Languages: Kotlin, Java, C++, Python • Android: Android SDK, Jetpack Compose, Android TV, Coroutines, Flow, MVVM, MVI • Networking: Retrofit, Ktor, GraphQL, REST APIs, WebSockets, MQTT, Protocol Buffers • Media: AndroidX Media3, ExoPlayer, Preloading and Playback Optimization • Architecture & Tools: Kotlin Multiplatform, Hilt, Room, Firebase, Gradle, CI/CD • On-Device AI: TensorFlow Lite, Google ML Kit, Google AI Edge SDK Key achievements: • Improved the QA feedback loop by 40% through an internal debugging suite. • Reduced network payload size by approximately 50% through JSON/Protobuf content negotiation. • Built a KSP-powered automated Themes SDK, reducing manual UI development effort by approximately 40%. • Solved 450+ DSA problems across LeetCode and GeeksforGeeks. • Secured a Top 10 finish at ParulHacks among 200 teams and won the Kriyeta 5.0 Hackathon. I enjoy solving challenging engineering problems, designing maintainable architectures, optimizing application performance, and building reliable user experiences at scale. I'm always interested in connecting with engineers, learning from innovative teams, and exploring opportunities to build impactful software.
