About

Mobile Engineer with 10+ years of experience building production mobile apps — primarily on Android, now also delivering cross-platform applications with React Native. I enjoy understanding how mobile systems work under the hood — from architecture and debugging to how different layers of the mobile stack interact. Over the past decade I’ve built and maintained large-scale mobile applications using Java and Kotlin, focusing on reliability, maintainability, and user experience. My work has included building applications for international products and contributing to complex mobile systems. Recently I’ve been working on React Native applications that run on both Android and iOS, which has expanded my understanding of cross-platform mobile development and how JavaScript runtimes interact with native mobile environments. My technical experience includes Android architecture patterns such as MVVM and Clean Architecture, along with technologies like Kotlin Coroutines, Jetpack libraries, dependency injection frameworks (Dagger/Koin), and reactive programming with RxJava. I’ve also worked extensively with REST APIs, push notifications, analytics, crash reporting, and CI/CD workflows. Outside of day-to-day work, I enjoy experimenting with new technologies and building personal projects using tools like Flutter and Kotlin Multiplatform. Key areas: Android • Kotlin • Java • React Native • Mobile Architecture • Debugging • Performance
