I'm an iOS engineer with 4+ years of shipping applications to production on the App Store. I build natively in Swift and SwiftUI, and I own the full release lifecycle - architecture, API integration, App Store Connect submission, and every update after it. If your app stutters on its heaviest screens, if you need a production-ready MVP built from scratch, or if you need someone who can take an app from an empty Xcode project to live on the App Store, I have the technical depth to deliver. How I solve your iOS engineering challenges: • Performance Optimization: I recently overhauled a complex enterprise application, cutting load times and eliminating UI stutter on its heaviest screens. • End-to-End Delivery: I solo-developed and shipped the REFA app from an empty repository to live on the App Store, architecting interactive MapKit views, deep linking, and a custom instalment payment gateway. • Enterprise Scale: At Bsma ERP I own the iOS client for a multi-tenant ERP product used to run daily business operations, built on SwiftUI and Clean Architecture. • Complex Feature Engineering: I built real-time eye-tracking research applications for high-stakes cognitive studies at The American University in Cairo. • Architectural Excellence: I strictly adhere to Clean Architecture, MVVM, SOLID principles, and dependency injection to keep your codebase maintainable and scaling effortlessly with your user base. Core Technical Stack: • Mobile: Swift, SwiftUI, UIKit, Swift 6 Concurrency • Architecture: Clean Architecture, MVVM, Dependency Injection, SOLID • Data & Integration: URLSession, Codable, REST APIs, Keychain, SwiftData, MapKit, Firebase, payment gateways, deep linking, push notifications • Release: Xcode, TestFlight, App Store Connect, CI/CD, GitHub Actions, Git My Commitment: I pride myself on writing clean, robust code and delivering exceptional UI/UX. Whether you are a startup seeking an MVP or an established business requiring a critical feature upgrade, I deliver on time and with technical precision. Ready to build something exceptional?
