What I'm looking for

I seek a role building end-to-end mobile products using Kotlin Multiplatform, emphasizing scalable architecture, analytics-driven growth, cross-functional collaboration, and opportunities to lead product and technical decisions.

I am a Senior Kotlin Multiplatform and Android engineer with 4+ years building production-grade mobile products for Android and iOS, including the StandProud app published on Google Play and the App Store.

I design and implement full-stack solutions using Compose Multiplatform, Ktor (client & server), PostgreSQL on GCP, SQLDelight, and DI frameworks like Hilt and Koin, applying Clean Architecture and MVI for scalable, maintainable apps.

Beyond development, I built backend auth and REST APIs, a workout-plan generation algorithm, subscription flows with RevenueCat, analytics pipelines (Firebase, GA4, Mixpanel), and led growth campaigns for acquisition and optimization.

I also contribute UX/UI design, produced and edited 500+ exercise videos with AI voiceovers, and collaborate with designers and physiotherapists to deliver data-driven, user-focused products.
