Darshika S.
Flutter & React Native Developer | AI-Powered iOS & Android Apps
I've worked on apps that ring like a real phone call on a locked iPhone, read a wine label through the camera, and take payments through Stripe, the App Store and Google Play. That's the mobile work I enjoy most: the parts that simply have to work. I'm Darshika, a mobile developer with 3+ years of experience in Flutter and React Native at Coretus Technologies. Most of the apps I've worked on are live on the App Store and Google Play right now. Apps I've worked on: - TalkMax: chat with HD voice and video calls, and iPhones that ring like a real phone call. Flutter, WebRTC, LiveKit, CallKit. - EAT: point your camera at the fridge, a wine list or your bar, and AI suggests what to cook or drink. Flutter, 83 screens. - Caletus: book and run meetings from your phone, with subscriptions through Stripe, the App Store and Google Play. Flutter. - MatjarDhahab: buy gold bars in English or Arabic, with live prices and a full right-to-left layout. Flutter, Riverpod. - Sudoku Master: a fully offline game with daily challenges, coins, ads and a Pro plan. React Native, Expo. - AlgoSuccess: live trading positions and profit and loss that update in real time. Flutter. Where I can help: you have an idea and need it in both stores, your app crashes, lags or got rejected, or you want to add AI like camera scanning or smart suggestions. If you've built a prototype with an AI tool and need it to pass review and hold up with real users, that's a job I like. How I work: you get a test build on your own phone every week, not just screenshots. If something won't work, I tell you early. Happy to start with a small paid task so you can judge my work first. Stack: Flutter, Dart, React Native, Expo, TypeScript, Riverpod, GetX, Firebase, Stripe, in-app purchases, WebRTC, LiveKit, CallKit, REST APIs. Tell me what your app needs to do and I'll reply with how I'd build it.
