Taras C.

Senior iOS / iPadOS / watchOS / tvOS / macOS Developer — 7 years, 15+ shipped apps, 1M+ users reached. I build native Apple apps end to end: idea → architecture → UI → App Store → post-launch iteration. Swift & SwiftUI first, clean architecture, and no shortcuts that cost you later. ✅ PROVEN RESULTS ⭐️ Shipped and maintained an app with 1,000,000+ users (core team of 3). ⭐️ Kept a 150,000-user app at 99.96% crash-free (team of 2). ⭐️ Led products from idea → design → refinement → implementation → release. ⭐️ 15+ delivered projects across iPhone, iPad, Apple Watch, Apple TV and Mac. ⭐️ Built my own apps: a spaced-repetition learning app (Ebbinghaus forgetting curve) and an enhanced music player. 🎯 WHAT I CAN DO FOR YOU ▸ Build a new iOS app from scratch — MVP in weeks, not quarters ▸ Rescue or refactor a legacy Objective-C / messy Swift codebase ▸ Kill crashes, memory leaks, slow launch time and laggy scrolling ▸ Get you through App Store review (rejections, privacy, ATT, guidelines) ▸ Add monetization: subscriptions, in-app purchases, paywalls, ads ▸ Port an iPhone app to iPad, Apple Watch, Apple TV, CarPlay or macOS ▸ Take over an abandoned project and actually ship it 🛠 TECH STACK 🟢 Languages: Swift, Objective-C, Python (basic) 🟢 UI: SwiftUI, UIKit, AutoLayout, SnapKit, Core Animation, WidgetKit, Live Activities, App Clips, Dark Mode, Accessibility / VoiceOver, Localization 🟢 Architecture: MVVM+C, VIPER, TCA, MVC, Clean Architecture, SOLID, Facade, Adapter, Decorator, Factory Method, Singleton, Builder, Observer, Command 🟢 Concurrency: Swift Concurrency (async/await, actors), GCD, OperationQueue 🟢 Reactive: Combine, RxSwift, ReactiveSwift, ReactiveCocoa 🟢 Networking: REST API, URLSession, Alamofire, Moya, AFNetworking, GraphQL (Apollo), WebSockets, Socket IO 🟢 Data: Core Data, Realm, SQLite, SwiftData, CloudKit, Keychain, Firebase Cloud Firestore, Firebase Realtime Database 🟢 Apple frameworks: Foundation, MapKit, Core Location, AVFoundation, AVKit, HealthKit, StoreKit 2, PassKit, EventKit, HomeKit, SiriKit, App Intents, PushKit, WatchKit, TVMLKit, WebKit, SpriteKit, Core Bluetooth, Core Motion, Core ML, Vision, Speech, Contacts, CarPlay 🟢 Services & SDKs: Firebase (Analytics, Crashlytics, Remote Config, Dynamic Links), OpenAI API, Stripe, Apple Pay, Twilio API, Google Maps, Google Places, Google AdMob, Facebook SDK, Sign in with Apple, Amplitude, Mixpanel, Sentry, RevenueCat, OneSignal 🟢 Quality & CI/CD: XCTest, unit & UI testing, Fastlane, Xcode Cloud, GitHub Actions, Bitrise, SwiftLint, Xcode Instruments, TestFlight, App Store Connect, code review 🟢 Tools: Xcode, Git, GitHub, Sourcetree, SPM, CocoaPods, Carthage, Figma, Sketch, Zeplin, Postman, Proxyman 🟢 Process: Agile, Scrum, Kanban, JIRA, Trello, ClickUp 💡 FEATURES I'VE SHIPPED In-App Purchases & subscriptions · Payment Gateway Integration · Push Notifications · User Authentication & User Profile Creation · Chat & Messaging · Map Integration & Location-Based Services · Bluetooth / BLE · Camera & Photo · Microphone & Audio · QR & Barcode Scanner · Offline Functionality & Sync · Deep Links & Universal Links · Social Media Account Integration · In-App Search · AI Text-to-Speech · Face Detection · Motion Sensors · Advanced Analytics & A/B Testing · In-App Advertising · Review & Feedback Collection · Application Security · API Integration · In-App Support 📦 SERVICES Native App Development · Mobile App Development · Mobile App Redesign · Mobile App Improvement · Mobile App Bug Fix · Mobile App Testing · Mobile App Localization · App Store Optimization · Mobile App Development Consultation · iPhone & iPad Apps · Apple Watch Application · Apple TV Application · macOS Application 🤝 HOW I WORK ✔️ Clear English, regular updates, no disappearing acts. ✔️ Your timezone matters — I overlap with both US and EU hours. ✔️ Estimates you can plan around, and a heads-up the moment something changes. ✔️ Clean, documented, testable code that you or your next developer can own. ✔️ NDA-friendly — your idea stays yours. Thanks for reading this far 🙂 Tell me what you're building, and I'll reply with an honest estimate plus the first thing I'd fix
