Senior iOS/macOS Developer - Native Swift, System Frameworks, AppStore

30 years writing software, the last several fully native Apple: Swift, SwiftUI, and the system frameworks most developers never touch — CoreMediaIO virtual cameras, ScreenCaptureKit, Accessibility-API automation, BLE device integration, CloudKit, StoreKit/RevenueCat, CarPlay entitlements. What I've shipped: - Consumer iOS/macOS apps on the App Store — pet-safety monitoring with CloudKit two-device pairing, a SwiftUI menubar calculator, BLE health-device apps that reverse-engineer defunct hardware to keep it alive, an ADV/supermoto navigation app with custom offroad routing and CarPlay integration, and voice-transcription utilities monetized end-to-end - System-level macOS — CoreMediaIO virtual cameras, ScreenCaptureKit capture, on-device AI overlays (WhisperKit + Foundation Models), and Accessibility-API automation that drives native apps with no exposed API - Full release pipelines — signing, notarization, App Store submission, and release automation, so "done" actually means shipped How I work: I've been writing code since before most of today's frameworks existed, and I've adapted deliberately — I run agentic coding tools (Claude Code and others) as part of my own toolchain to move faster on scaffolding and boilerplate, while architecture, system-level design, and final code quality stay mine. That combination is the point: three decades of judgment about what's actually going to work, paired with modern velocity. I take full ownership from concept to shipped product. I'm also comfortable stepping into a technical-lead role — setting architecture, untangling systems that have outgrown their original design, and giving a project the structure it's missing. Best fit for clients who need senior-level execution on hard, native Apple problems: someone who owns it end to end rather than waits for specs. Message me — happy to talk specifics.
