I build apps that feel right on iOS and help them grow through ASO and Ads. 𝟭𝟬 𝘆𝗲𝗮𝗿𝘀 𝗶𝗻 𝗶𝗢𝗦 𝗱𝗲𝘃𝗲𝗹𝗼𝗽𝗺𝗲𝗻𝘁 · 𝟮𝟬+ 𝗮𝗽𝗽𝘀 𝘀𝗵𝗶𝗽𝗽𝗲𝗱 · 𝗦𝘄𝗶𝗳𝘁 · 𝗦𝘄𝗶𝗳𝘁𝗨𝗜 · 𝗨𝗜𝗞𝗶𝘁 🤖 AI-enabled development with Codex & Claude for faster implementation, iteration, and delivery. I use AI throughout my development workflow while personally reviewing the architecture, technical decisions, and final quality. You get the speed and efficiency of modern AI tools backed by real hands-on iOS development experience. Whether you’re starting a new mobile app or improving an existing product, I can take ownership of the iOS side – from architecture and development to App Store release. As an experienced iOS developer, I specialize in native mobile app development across Apple platforms: – iOS & iPad app development (Swift, SwiftUI, UIKit) – macOS development (SwiftUI, AppKit) – watchOS & tvOS development – AI mobile app development and AI integrations – Consulting for Apple-native software projects Over the years, I’ve worked with a wide range of Apple frameworks, third-party SDKs, APIs, and backend services to build production mobile apps. My iOS development experience includes: – Languages, UI & Architecture: Swift, Objective-C, SwiftUI, UIKit, AppKit, TCA, MVVM, Clean Architecture – Backend, Auth & API Integration: Firebase, Supabase, AWS, Firebase Auth, Sign in with Apple, OAuth, REST APIs, GraphQL – Networking: URLSession, Alamofire, WebSockets, WebRTC – Data Persistence: SwiftData, Core Data, CloudKit, Realm, SQLite – Media & Vision: AVFoundation, Photos, Core Image, Kingfisher, Lottie, Vision, VisionKit, Speech, PDFKit – Device & Platform: MapKit, CoreLocation, HealthKit, CoreBluetooth, Core NFC, WidgetKit, ActivityKit, FamilyControls, DeviceActivity, ManagedSettings – AI & Machine Learning: Core ML, MLX, llama.cpp, OpenAI API, OpenRouter – Analytics & Attribution: Firebase Analytics, GA4, Mixpanel, Amplitude, AppsFlyer, Adjust, Crashlytics, Sentry – Payments & In-App Purchases: StoreKit, RevenueCat, Superwall, Stripe – System Frameworks: WebKit, PassKit, UserNotifications, BackgroundTasks My work doesn’t have to stop when your iOS app reaches the App Store. I can also help with launch, monetization, analytics, attribution, and growth: – App Store submission and review issues – ASO and App Store conversion optimization – Apple Ads setup and optimization – RevenueCat, subscriptions, paywalls, and in-app purchases – Analytics, attribution, and conversion tracking – ROAS measurement and post-launch product analytics When you hire me as your iOS developer, you work directly with me – not an agency, account manager, or junior developer. I personally stay involved from the first discussion through mobile app development, testing, and App Store release. I’m comfortable taking ownership of both new mobile app development projects and existing production codebases, and I bring a product-minded approach rather than simply implementing tickets. Send me a quick message and we’ll go over your idea in detail over a video call or Upwork chat.
