Share your idea, and I'll turn it into a production-ready app that solves real problems and generates revenue. 10+ marketplace and booking apps live on the App Store and Play Store — real Stripe payments, multi-role systems, and Firebase backends serving actual users. Top Rated on Upwork with a 100% Job Success Score across 20+ delivered projects. Most Flutter developers can build a screen. Fewer can architect a two-sided marketplace with split payments, real-time chat, dispute handling, and an admin panel that a business actually runs on. That's the work I specialize in. WHAT I'VE BUILT - CookHire — two-sided marketplace with Stripe split payments, in-app chat, and a dispute system. Live on both stores. - A 24-module operations dashboard ported from web to mobile (95+ Dart files, clean architecture). - Booking and scheduling apps with provider calendars and multi-role access. - Several production apps shipped end-to-end — from Figma to App Store approval. WHAT I DO WELL - Marketplace platforms — customer / provider / admin roles, Stripe payments, admin panels - Booking & appointment systems — calendars, scheduling, availability logic - Startup MVPs — clean architecture from day one, built to scale, not just demo - Firebase — Auth, Firestore, Cloud Functions, FCM, security rules done properly - REST API integration — proper auth, pagination, and real error handling - Fixing existing Flutter apps — performance, bugs, and new features on messy codebases TRACK RECORD ✅ 20+ projects delivered — 100% Job Success, Top Rated on Upwork ✅ 10+ Flutter apps live on App Store & Google Play ✅ Marketplace & booking apps with Customer / Provider / Admin role systems ✅ Stripe integrations — service fees, split payments, escrow-style flows ✅ Firebase backends — Auth, Firestore, Cloud Functions, real-time data HOW I WORK You get regular Git pushes and milestone updates — never a "where's my project" moment. I scope the full picture before writing code, choose the right architecture (Provider / Riverpod / Bloc) for your app's real complexity, and handle both store submissions myself. After launch, I'm available for fixes and new features.
