I help companies modernize, rescue, and ship production iOS apps. I'm currently a consulting engineer for 1Q, a consumer insights platform, and previously spent 8 years as the senior iOS engineer behind Realm — church management apps serving 50,000 churches — plus two years building retail apps for Victra, Verizon's largest authorized retailer. If your app needs a SwiftUI migration, a performance overhaul, or a senior engineer who owns delivery end-to-end, that's what I do. What I can do for you: Legacy modernization — Migrate Objective-C and older UIKit codebases to Swift and SwiftUI incrementally, without halting feature work. I've guided one production app through every major iOS transition since 2015. AI-accelerated development — I use AI-assisted engineering workflows (adopted leading retail app development at Victra) to deliver senior-quality code faster, and I can help your team adopt them too. App rescue & performance — Diagnose crashes, memory leaks, and slow UIs with Instruments and structured profiling, then fix the architecture underneath. Quality & delivery infrastructure — Unit and UI test coverage (XCTest, XCUITest) and CI/CD pipelines in GitHub Actions or Azure DevOps so your team ships confidently. Why clients work with me: Every rating on my profile is 4.9 or 5.0, and clients describe me as proactive and a clear communicator — I flag risks early and explain tradeoffs in plain language. I also ship my own products: my language-learning apps Foreign Words and Fremdwörter are live on the App Store, fully localized in seven languages. I know the entire lifecycle from architecture to App Store approval because I've done it solo and at enterprise scale. I'm US-based in North Carolina (Eastern Time) with full overlap with US business hours. A good first step: many engagements begin with a fixed-price iOS App Audit — architecture, performance, test coverage, and App Store readiness, delivered as a prioritized action plan. Message me and tell me about your app. A note on cross-platform work: AI app builders often generate React Native rather than native Swift. I have been doing hands-on React Native and Android work for a current consulting client since January 2026, so if your AI-built app turned out to be cross-platform, I can still finish it and ship it to both the App Store and Google Play.
