An iOS developer who takes apps from idea to millions of downloads. I built Struckd (12M+ downloads, acquired by Unity Technologies) and Daily Dozen (1M+ downloads, 4.9 rating, featured by Apple). 14+ years shipping Swift, SwiftUI, and React Native. 30M+ client app downloads total. Most developers write code. I handle the entire product lifecycle - architecture, development, App Store submission, ASO, growth, and ongoing support. You focus on business and marketing, I handle everything technical. Need someone to drop into an existing codebase and ship features instead? I do that just as well. Whatever the project needs. iOS native is my strongest skill - Swift, SwiftUI, SwiftData, UIKit, and Combine since day one, with a large library of reusable components for fast shipping. I also work deep in: - Android - Kotlin, Jetpack Compose, Kotlin Multiplatform, Compose Multiplatform - Cross-platform - React Native, Expo, Flutter - AI integration - Claude API, OpenAI, CoreML, on-device ML, spec-driven AI-assisted development - Specialized - HealthKit and medical apps, BLE hardware, fintech, and game dev (Unity, ARKit, SceneKit, Metal) Growth is built in. I created ASOFast to solve App Store optimization at scale. I've gotten multiple apps featured by Apple and know the review process inside out. I also ran the CosmicTaps iOS portfolio (9M+ downloads). Former CTO, Head of Mobile, and Tech Game Producer. If you need a developer who ships clean, scalable code, that's me. If you also need someone who thinks about the business value of what they're building, you won't find that combination twice. Tell me what you're building, and I'll tell you exactly how I'd ship it.
