I've shipped 20+ iOS apps to the App Store with a 98% crash-free session rate — including subscription apps monetized through StoreKit and RevenueCat. If you need an app built, fixed, or shipped, I handle everything from architecture to App Review approval.
Most of my clients come to me for one of three things:
🔧 Rescuing broken apps — crashes, background audio failures, layout bugs, memory leaks. I recently fixed a Lovable-built iOS app's background audio in under a week (5-star review below). I also work with Capacitor/hybrid apps, where I know exactly where web-to-native builds break.
📱 Building SwiftUI apps from scratch — MVP to App Store in weeks, not months. I've built everything from a workout app with live sessions and dual-tier subscriptions to a professional drawing engine with Apple Pencil pressure support, using only native Apple frameworks.
💰 Subscription & monetization setup — StoreKit, RevenueCat, APNs, and the full TestFlight-to-App-Review release pipeline. I've managed provisioning, review submissions, and post-launch iteration across 20+ production apps.
What you get working with me: async/await networking that cuts boilerplate by 40%, Core Data tuned for speed (30% faster retrieval on past projects), and memory-leak-free builds verified through Xcode Instruments — not just an app that works in the demo, but one that survives real users.
Send me your app idea, your broken build, or your App Store rejection — I'll reply within 24 hours with a concrete plan and timeline.
