Projects

A productivity-focused iOS app that helps users track their daily LeetCode problem-solving progress through home screen widgets. Uses SwiftUI WidgetKit for live stats, App Groups + UserDefaults for real-time data sharing between the app and widget, and timeline-based background refresh.

A high-performance, MVVM-based feature set built for Apple's in-house productivity suite, boosting user engagement. Integrated SwiftKeychainWrapper for securely storing sensitive data, and implemented audio playback controls (play, pause, skip) using AVKit.

A SwiftUI navigation package with custom transitions, deep linking, and programmatic navigation for flexible app flows. A modular navigation service supports stack tracking and multiple operations (push, pop, replace) for maintainable code, with fade, slide, and scale animations.
