I’m a Mobile App Developer with hands-on experience building, converting, publishing, and maintaining production-ready iOS and Android applications using React Native, Flutter, Capacitor, Ionic, Vue, and Quasar. I can take your mobile app from development → API/backend integration → testing → App Store/Google Play submission → production maintenance. 📱 Mobile App Development React Native app development Flutter & Dart Capacitor & Cordova Ionic / Angular Vue / Quasar iOS & Android app development Convert existing web applications into mobile apps Custom native integrations and plugins REST API & backend integrations 🚀 Published Production Apps I have worked on and shipped applications that are live on both the Apple App Store and Google Play Store, including applications used by real users. ClinicOne — Healthcare Mobile Application AutoBroker — Automotive Marketplace Application These projects involved real-world API integrations, authentication, location-based functionality, mobile UI, backend integration, production releases, and app-store deployment. 🔥 Firebase & Backend Firebase Authentication Firestore Firebase Storage Firebase Cloud Functions Firebase Cloud Messaging (FCM) Push notifications REST API integration Google Cloud integrations 💳 Payments & Third-Party Integrations Stripe Razorpay Payment gateway integration Google / Facebook / Apple / LINE login Phone OTP authentication Google Maps & location-based features Third-party API integrations 🎬 Video & Audio Development FFmpeg Video processing Audio processing Video conversion and compression Media manipulation Automated video/audio processing tools 🍎 App Store & Google Play Publishing I can also handle the complete mobile app publishing lifecycle: Apple App Store submission Google Play Store submission App signing & certificates iOS provisioning profiles Play Console configuration App Store / Play Store compliance Production releases and updates Troubleshooting publishing and review issues 💼 What I Can Help You With ✔ Build a mobile application from scratch ✔ Convert an existing website/web app into iOS & Android apps ✔ Build cross-platform apps with React Native, Flutter or Capacitor ✔ Fix and improve existing mobile applications ✔ Integrate Firebase, APIs, payments, maps and notifications ✔ Implement authentication and social login ✔ Publish applications to the Apple App Store and Google Play ✔ Develop video/audio processing features using FFmpeg ✔ Maintain and improve existing production applications I focus on clean implementation, reliable communication, production stability, and long-term maintainability.

I build Flutter apps that ship — not prototypes that stall at 80% done. Over the past 4+ years I've taken 30+ mobile products from a blank repo to the App Store and Play Store, including AI-powered apps, FinTech tools, and real-time platforms used by paying customers today. If you need a developer who can own the full build — architecture, AI integration, backend, deployment — you're in the right profile. What I actually solve for clients: * You have an idea or a stalled project and need someone who can architect it correctly the first time, not patch it later * You want AI features (OpenAI, Gemini, Claude, custom LLM workflows) built into a real product, not a demo * You need Firebase set up properly — Auth, Firestore, Cloud Functions, FCM — so it scales past your first 1,000 users * You want both Flutter and native iOS (SwiftUI) capability under one contractor instead of coordinating two teams Recent work includes: * AI-powered health and fitness apps with OpenAI-driven personalization * Real-time chat and social apps built on Firebase + Socket io * FinTech apps with secure payment gateway integration * NFC-enabled apps for access control and card reading/writing * Alarm and background-service apps requiring native platform depth beyond standard Flutter plugins How I work: * Clean Architecture, testable code, and documentation — so your next developer (or I, six months later) isn't guessing * Direct, frequent communication — no disappearing between milestones * I scope realistically upfront; I don't pad timelines to inflate hours, and I don't lowball to win the job then stall Tech stack: Flutter, Dart, FlutterFlow, SwiftUI, Firebase (Auth, Firestore, Cloud Functions, FCM), REST APIs, OpenAI/Gemini/Claude API integration, Provider, Riverpod, Bloc, GetX, Socket io, Google Maps, NFC, payment gateways. If your project needs someone who can go from Figma file to App Store approval without handing off pieces to three other freelancers. Send me a message with what you're building and I'll tell you honestly whether I'm the right fit.
