Top Rated Plus | 80 jobs | 5,244 hours | 10 years building mobile apps | 20+ apps published on the App Store and Google Play If you've built something in React, Next.js, Vite, a PWA, or on Lovable, Replit or Base44, and it now needs to be a real iOS and Android app, that conversion is what I do more than anything else. I keep your backend, database, auth and Stripe flows intact and handle the native side properly: push notifications, in-app purchases, background tasks, deep links, signing, and the App Store review process. You don't get a rewrite and you don't get a second developer.

Native plugins when the one you need doesn't exist — I've written around thirty, Java and Kotlin on Android, Swift on iOS. Hardware that has to talk to the app: thermal and label printers, card readers, scanners, Bluetooth devices, sensors. Offline-first apps that keep working with no signal and reconcile later. And apps nobody has maintained in two years. AI FEATURES I add AI where it belongs, inside real apps. Chat assistants, AI-driven analysis, OpenAI, Claude and Gemini APIs. Wiring up an endpoint is the easy part. Making it behave inside an app that also runs offline, syncs, handles auth and payments and passes store review is the actual work. HOW I WORK I read your codebase and confirm scope before writing a line. You get a clear plan, honest answers about what's realistic, and an early warning if your app's category or content is likely to run into App Store or Play Store policy problems, before you spend money finding out. I do the work myself, so you're always talking to the person building your app. Tell me where your project is now and I'll tell you exactly how I'd take it to the stores.
