I've built and shipped cross-platform Android and iOS features for PushScroll, including streaks, calendar views, widgets, notifications, rewards, and Picture-in-Picture. I integrated AVPlayer, UserNotifications, FileManager, and Apple FamilyControls into shared Kotlin Multiplatform architecture.

At ReelShop and WebSchool, I led Kotlin Multiplatform development for e-commerce and education products. I designed shared business logic, media caching and playback, real-time messaging, push notifications, MVI architecture, and reliable browsing, search, cart, and purchase flows.

I've improved production reliability through Sentry tracking, analytics instrumentation, unit tests, performance profiling, ANR debugging, and Clean Architecture refactoring. At Annodoc, I improved large-PDF loading and rendering performance by 30% through concurrent processing and memory optimization.

I also contribute to open source and developer tooling, including ComposeMediaPlayer, Compose Rich Text Editor, and Softy KMP Wizard. I use AI extensively for exploration, implementation, refactoring, debugging, and problem solving, validating solutions through tests, documentation, and first-principles reasoning.
