Senior Swift & Native Dev: Rescue, Finish and Ship Your App / Game

Your app is 80% done and stuck? That's where I come in. I take prototypes built with AI tools, or projects a previous developer left behind, and turn them into native apps that actually ship: App Store approved, stable, and fast. Top Rated Plus, $300K+ earned, 30 years writing software. The last several years fully native Apple, plus Windows and Android. What I solve most often: - AI-built or half-finished apps that need to become real iOS, macOS or Windows apps - App Store rejections, signing, notarization and release pipelines - The hard native parts AI tools can't do: CarPlay, Bluetooth/BLE hardware, CoreMediaIO virtual cameras, ScreenCaptureKit, Accessibility automation, CloudKit, StoreKit/RevenueCat, Critical Alerts - Hardware and kiosk integrations: payment terminals, printers, cameras, custom devices - Windows desktop apps in C#/.NET/WPF, and native Android in Kotlin What I've shipped: - An offline motorcycle navigation app with on-device routing and CarPlay - A pet-safety app using Apple's Critical Alerts entitlement and CloudKit device pairing - Webcam drivers for macOS and Windows, and a BLE hardware keyboard driver - A native desktop assistant with WebRTC echo cancellation, screen reading and overlays - A co-op multiplayer game in Unity with a dedicated server Before software I spent 25 years in woodworking production and CNC programming (Homag woodWOP, Biesse, InteriorCAD), so I also build CAD/CAM tools and post-processors that workshops actually use. I use modern AI coding tools myself to move fast, but architecture, system design and final quality stay mine. That's exactly why I can pick up where AI-built apps get stuck. Send me what you have, even if it's messy. I'll tell you honestly what it takes to ship it.
