About

I am a Senior Android Developer with 7+ years of experience delivering mobile apps for international clients. I specialize in cross-platform mobile solutions using Kotlin Multiplatform and have worked on Android since the early alpha days. I enjoy building scalable architectures and shipping high-quality software for diverse domains.

My focus areas include mobile software architecture, Kotlin Multiplatform for Android + iOS app business layers, Jetpack Compose UI, and SDK development. I routinely work with Kotlin & Java, Bluetooth Low Energy, and native C++ via JNI to create robust native integrations for health, fitness, location-based marketing, and other verticals.
