A production-ready SwiftUI app demonstrating MVI (Model-View-Intent) architecture with unidirectional data flow, predictable state management, and testable side effects. Features single source of truth state management, explicit user events via Intents, pure state transitions with Reducer pattern, and comprehensive unit tests.
Professional macOS diagnostic and crash reporting application built with Objective-C and integrated with Sentry SDK + MetricKit. Features real-time network monitoring, comprehensive system log collection with automatic PII redaction, multiple crash testing scenarios, and diagnostic bundle export capabilities.
SwiftUI application showcasing reactive programming with Combine framework. Implements MVVM architecture with debounced text input, reactive networking, async image loading, pagination, and offline-friendly caching for GitHub user search.
A structured 30-day learning journey mastering React and React Native from a mobile engineer's perspective. Covers modern JavaScript (ES6+), JSX, components, state management with hooks, and culminates in a capstone React Native application.
