Basit M.

Flutter & Native Android Developer | 4+ Years | 55 Projects Delivered Flutter | Dart | Kotlin | Firebase | Supabase | API Integration | OpenAI | iOS | Android I build production Flutter and native Android apps, backed by Firebase, Supabase and custom backends, including AI-powered apps. I’ve delivered 55 projects across marketplaces, booking platforms, e-commerce, AI tools and enterprise SaaS. Most clients come to me with one of three problems: an idea that needs building, an app that stalled halfway, or a codebase a previous developer left behind. I handle all three end to end (mobile app, backend, admin panel and store submission), so you work with one developer instead of three. ✅ WHY CLIENTS HIRE ME 4+ years of Flutter and native Android development 55 projects delivered for clients in Belgium, the UK, Turkey, Nigeria and the US End to end: UI, mobile app and backend in one place Clean, scalable architecture your next developer can read Clear communication and regular progress builds, no silent weeks 📱 MOBILE APP DEVELOPMENT Cross-platform iOS and Android apps with Flutter and Dart Native Android apps with Kotlin and Java Pixel-perfect UI from Figma or written requirements State management: Bloc, Riverpod, Provider, GetX Clean Architecture and MVVM Performance optimization, refactoring and legacy code rescue 🧠 AI APP DEVELOPMENT OpenAI, Claude and Gemini API integration In-app AI chat, assistants and smart recommendations Document scanning, OCR and image processing AI calls routed through server-side functions to protect API keys and control costs 🔥 FIREBASE, BACKEND & API INTEGRATION Firebase Authentication (email, Google, Apple, phone) Cloud Firestore, Cloud Storage, Cloud Functions Supabase setup and integration Node.js and NestJS services, PostgreSQL, MongoDB REST API development and integration with JWT auth Push notifications (FCM), analytics and crash reporting 💳 PAYMENTS & INTEGRATIONS Stripe, PayPal, Paystack, RevenueCat, in-app purchases Subscriptions, paywalls and free-trial logic Google Maps API, geolocation and live tracking Real-time chat and messaging 📲 SELECTED WORK ▸ AI Digital Receipt App Flutter app that stores receipts digitally and uses AI to [confirm: read receipt photos, extract amounts and dates, categorize spending].
