Additional information

I am a motivated Mobile developer from Ukraine who is passionate about my work. Over the past 8 years, I have developed a wide range of applications. Having worked remotely throughout my career, I am highly self-disciplined and proficient in time management.

Outside of work, I lead an active lifestyle and enjoy various sports, including running, snowboarding, hiking, cycling, kettlebell training, ping-pong, swimming, and hitting the gym.

I have worked on B2C mobile products, media and streaming applications, Android TV solutions, and subscription and payment functionality. My responsibilities covered the full development lifecycle, from architecture design and UI implementation to API integrations, performance optimization, video streaming, and Google Play releases.

My core stack includes Kotlin, Java, Coroutines, Flow, MVVM/MVI, SOLID, Clean Architecture, AndroidX, Retrofit, OkHttp, Room, Firebase, HLS/DASH/VOD, REST, Play Store and CI/CD. I also have strong expertise in Kotlin Multiplatform for Android and iOS and actively use AI tools in my development workflow. Codex is my personal favorite.

I work as a Senior Mobile Developer, taking ownership of technical decisions, code quality, and feature delivery. Going forward, I want to deepen my expertise in KMP and the architecture of complex products, while also expanding my cross-platform experience by learning Flutter and React Native.
