I specialize in stabilizing and modernizing iOS codebases — crash recovery, legacy rewrites, architecture cleanup, and long-term system ownership. I've worked across production systems at enterprise scale. iOS Engineering — Swift, SwiftUI, UIKit, Objective-C, Combine, Swift Async/Await Architecture — MVVM, Clean Architecture, VIPER, Coordinators, Modular Systems, Dependency Injection, SOLID iOS Frameworks — CoreData, CoreLocation, CoreMotion, CoreImage, Vision Framework, BackgroundTasks, AVFoundation, HLS, User Notification (push notifications) UI & Animation — Lottie, Kingfisher, SDWebImage, Nuke, SnapKit, AVFoundation Concurrency & Stability — Swift Async/Await, Combine, crash recovery, performance optimization, memory management Data Persistence — SwiftData, CoreData, SQLite, KeychainAccess Backend & Auth SDKs — Firebase, Supabase Swift, REST APIs AI Integration — OpenAI SDK, OpenRouter, vector embeddings (pgvector), NestJS/TypeScript backends CI/CD & Tooling — Fastlane, GitFlow, Swift Package Manager, CocoaPods, Carthage, SwiftLint, Xcode Cloud Analytics & Observability — Firebase Analytics, Sentry, crash reporting, performance monitoring App Store & Compliance — App Store Connect, App Store submission, review guidelines, rejection resolution, privacy compliance Accessibility — VoiceOver, WCAG, EAA compliance, full accessibility audits Databases — PostgreSQL, MySQL, MongoDB, SQLite, CoreData Testing — XCTest, unit testing, integration testing I can also assist you with app distribution, marketing, and launch using: — App Store Connect — Apple Developer Platform I work best on long-term contracts where I can own the system, not just patch it. If your iOS codebase is getting harder to maintain, slower to ship, or failing under growth — that's exactly the problem I solve. Send me a message — happy to jump on a call and go over the details.
