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.

I help indie developers and small startups with their iOS and macOS apps. WHAT I DO: • Build iOS/macOS MVPs for startups (fast turnaround) • Debug complex iOS issues (memory leaks, crashes, performance) • Fix App Store rejections and handle submissions • Maintain and update existing apps (iOS version compatibility, bug fixes) • Build new features using Swift, SwiftUI, UIKit • Menu bar apps (utilities, timers, quick-access tools) • Productivity and automation tools • macOS utilities with native look and feel • Apps using SwiftUI, AppKit, or hybrid • iOS, Swift, SwiftUI Mentoring WHY ME: • 10+ years focused on iOS development • 10+ published apps on the App Store (iOS, macOS, watchOS) • Led development team for 7 years (Club Operations - acquired by NorthStar) • Udemy instructor with 11,000+ students trained • Currently building with AI-assisted workflows (3-5x faster delivery) • Eye Rest Timer - Menu bar app for the 20-20-20 rule (Mac App Store) • Honest Hours - Privacy-first time tracker with auto-tracking IDEAL PROJECTS: • "My app is crashing and I don't know why" • "Apple rejected my app, need help fixing it" • "I need someone to maintain my iOS app" • "Add a feature to my existing app" • "I need a menu bar utility for X" • "Convert my iOS app to macOS" • "Build a desktop tool for my team" • "Create a Mac version of my web app" I respond quickly and communicate clearly. Let's talk about your project.

Most clients come to me after a bad experience. A developer who went quiet mid-project. An agency that looked great on the call and disappeared after the deposit. Or they're posting a job and genuinely don't know how to tell who's worth trusting. I get it. Hiring a senior iOS/macOS developer or AI developer you've never met, for a product that actually matters to you, takes a leap. So here's what I can offer instead of asking you to just trust me: - a 100% Job Success Score built over real client relationships, - a 7+ month active partnership with a SaaS client where I delivered 3 production apps, - and a track record where 70%+ of projects turn into ongoing work. Not because I pitch retainers, but because the work holds up. I specialize in native iOS/macOS development and AI-powered products. I take full ownership from architecture to deployment and stay invested in whether what I build actually moves your business forward. Core technical depth: - Native iOS & macOS development (Swift, SwiftUI) - AI-powered apps and intelligent product features - Python backends, APIs, Firebase, Supabase - Audio, vision, and NLP-based AI systems - Clean architecture built for long-term maintainability and scalability If you're building something serious and need a partner who thinks about your product the way a technical co-founder would, let's talk.
