I build scalable, crash-free native iOS applications with clean architecture and solid maintainability. Focused on delivering production-ready Apple ecosystem solutions from MVP conceptualization to full App Store deployment. Core expertise: • iOS application development: Full lifecycle engineering for enterprise software, native consumer apps, and complex mobile platforms. • Architecture & code quality: Scalable system design using MVVM, MVC, and MVP patterns with strict adherence to SOLID principles. • User interface engineering: High-performance dynamic UI creation using SwiftUI, UIKit, programmatic layout, size classes, and Storyboards/XIBs. • Reactive programming: Asynchronous state management and event handling using Combine, RxSwift/RxCocoa, and ReactiveSwift/ReactiveCocoa. • Networking & data persistence: Reliable REST API integrations, server communication (Alamofire, Moya, Kingfisher), and local persistence (CoreData, Realm). • Testing & stability: Comprehensive Unit and UI testing, automated crash reporting, proactive debugging, and CI/CD alignment. Technical stack: 🔹 iOS Frameworks & Apple SDKs SwiftUI, UIKit, Foundation, Combine, MapKit, CoreLocation, AVFoundation, Notification Center, Contacts, Keychain, WebKit, ARKit 🔹 Networking, SDKs & Third-Party Integration: Alamofire, Moya, REST API, Kingfisher, Firebase, Crashlytics, OpenCV, Google Maps SDK, Auth & Social SDKs (Facebook, Twitter, LinkedIn, Google) 🔹 Databases & persistence: CoreData, Realm Tools & version control: Xcode, Git, Unit Testing, UI Testing I don't require micro-management. Give me the business constraints, and I will deliver a maintainable, high-performance iOS product. Let’s discuss your current app state and where your architecture is failing.
