What I'm looking for

I'm available for remote full-time, part-time, and project-based work, and I'm open to occasional business travel.

At Performance EdTech LLC, I built and maintained iOS and Android applications from scratch, covering architecture, navigation, state management, and core infrastructure. I developed course and personalized-content features, offline downloads, and Stories/Reels-style interfaces.

I also developed native iOS functionality with Swift, SwiftUI, WidgetKit, and ActivityKit, connecting Widgets, Live Activities, and Dynamic Island integrations to React Native. Across my work at Mercury Development, Dragon Family LLC, Drimsim, and XCritical Software, I’ve developed offline-first and hardware-integrated features, subscriptions and payments, and mobile products for several domains.
