I'm a Senior Android Engineer with 9+ years of experience building and owning production mobile applications across Retail, Fintech, EdTech, Sports, Healthcare, Transportation, and Social products. My core expertise is Kotlin, Jetpack Compose, modern Android architecture, and Kotlin Multiplatform (KMP). I've built production KMP applications for Android and iOS with ~80% shared code, including shared UI with Compose Multiplatform. I’m comfortable taking a product from architecture to production independently — designing the architecture, writing the code, setting up CI/CD, managing releases, and maintaining the codebase long-term. Some highlights: • 10+ production mobile applications shipped • 2,000+ active users of an internal retail application • ~40% improvement in customer-service workflow efficiency after moving from a desktop-based workflow to mobile • 100K+ downloads for an EdTech application • 2 production KMP applications released for Android and iOS • ~80% shared code across Android and iOS I also have experience with: Kotlin • Jetpack Compose • Compose Multiplatform • KMP • Coroutines/Flow • Ktor • SQLDelight • Room • Retrofit • GraphQL • WebSockets • Hilt/Koin • Clean Architecture • MVI/MVVM • Multi-module architecture • Gradle • GitLab CI/CD • Firebase Beyond coding, I’m comfortable with technical planning, estimation, code and architecture reviews, and making decisions that shape the mobile technical direction. I work well both independently and in cross-functional teams, collaborating with Product Managers, CTOs, designers, clients, backend engineers, and other developers.
