100+ apps shipped to the App Store and Google Play, including a social platform with 50M+ downloads. Based in Minnesota, so US clients get real timezone overlap. 𝗔𝗜-𝗶𝗻𝘁𝗲𝗴𝗿𝗮𝘁𝗲𝗱 𝗺𝗼𝗯𝗶𝗹𝗲 𝗮𝗽𝗽𝘀. Claude and OpenAI APIs, streaming responses, image analysis, structured output, and the async job architecture these features need so a 30-second model call doesn't leave a user staring at a spinner. 𝗧𝗮𝗸𝗶𝗻𝗴 𝗼𝘃𝗲𝗿 𝗲𝘅𝗶𝘀𝘁𝗶𝗻𝗴 𝗰𝗼𝗱𝗲𝗯𝗮𝘀𝗲𝘀. Apps built by a previous developer, or generated with Lovable, Base44, Cursor or Claude Code, that need auditing, hardening and finishing. I read what's there before changing it, and I tell you honestly which parts are worth keeping and which aren't. 𝗚𝗲𝘁𝘁𝗶𝗻𝗴 𝗮𝗽𝗽𝘀 𝘀𝗵𝗶𝗽𝗽𝗲𝗱. TestFlight and App Store submission, Play Console releases, RevenueCat and StoreKit subscriptions, SDK and targetSdk migrations, and debugging the builds that work in development and crash in release. Stack: React Native, Expo and EAS, Flutter, native Swift and SwiftUI, native Kotlin and Compose. Backends in Node, FastAPI, Firebase and Supabase. Much of my client work is under NDA, so my public portfolio is a subset of what I've built. Happy to walk through anything privately. I work solo, I test on real devices before handing anything over, and I use Claude Code and Cursor daily while reviewing everything they produce. Based in Rosemount, Minnesota, so US clients get real timezone overlap. If you have an app that's stuck, half-finished, or needs an AI feature that actually works in production, send me the details and I'll tell you straight what it needs.
