Building a complete local digital ecosystem like SANGI requires a solid foundation in Flutter and Firebase. The Razorpay Payment Gateway integration is a crucial aspect of the project. To ensure a smooth and secure payment flow, I'd focus on implementing the Razorpay API and handling payment verification and transaction records. I've worked on similar projects, like the TradersHub app, where I had to integrate payment gateways and ensure a smooth user experience.

Hi there, I have thoroughly reviewed your requirement and got the actual problem with the current application structure, incomplete modules, architecture inconsistencies, and production-readiness gaps, and I along with my team can handle the complete transformation of the existing SANGI app into a stable, scalable, and Play Store ready application. Look, we have deployed 100+ Flutter based applications along with Firebase integrations, payment systems, admin panels, AI-powered features, real-time systems, and scalable backend architecture, so we are very comfortable handling projects like this. For the budget and timeline, I will share all this in a proper document after a quick discussion on few important things, and that document will include detailed budget, timeline, team involvement, technical approach, architecture restructuring plan, and complete development flow from current project audit till production deployment. I would request to connect for a quick discussion so we can review the current codebase and align properly before moving further. Thanks, Rahul A.

I’ve gone through your SANGI project requirements in detail and I understand the current situation clearly — that the app is already partially developed in Flutter with Firebase but needs full cleanup, completion, optimization, and preparation for production release. I can help you in analyzing the existing codebase, fixing architecture issues, cleaning broken modules, completing missing features, and making the entire system production-ready for Play Store deployment with proper performance, security, and scalability. This is a complex, real-world marketplace application involving multiple modules like users, providers, bookings, wallet, payments, location services, and admin control, and I have solid experience working on similar Flutter + Firebase-based scalable applications. Before giving a final cost and timeline, I would need a bit more clarity on: 1. Current project access (GitHub / ZIP / Firebase setup) 2. List of working vs non-working modules 3. Any specific UI references or changes expected 4. Whether the admin panel already exists or needs to be built from scratch I can also share relevant Flutter + Firebase projects I’ve worked on so you can review my experience. If needed, we can also schedule a quick call to go through the current code and plan the next steps properly. I’m ready to start immediately once we finalize the scope.

This SANGI app is less a “build features” task and more a system recovery + architecture correction problem. When a Flutter + Firebase project already exists with broken modules, the real risk is compounding inconsistencies instead of stabilizing a clean core. I’d start with a structured audit of the current codebase—routing, state management, Firestore schema, and auth flows—to identify what is salvageable versus what needs refactoring. The priority is to stabilize the foundation (clean architecture with repository pattern + consistent data models) before touching UI or adding new modules. Once the core is stable, I’d align Firebase structure around strict role separation (users, providers, admin) with secure rules, then rebuild booking, wallet, and notifications as isolated services rather than tightly coupled logic. That prevents the system from breaking as payments, chat, and marketplace features expand. Given the scope, I’d also enforce a proper CI/build pipeline early so Play Store readiness doesn’t become a last-minute issue again. If you have the current repo, I can quickly map technical debt and outline a realistic recovery plan before any further development begins.

I recently completed a project similar to yours, achieving optimized load times and a streamlined system. I am new to Freelancer, bringing vast experience from large-scale projects in ecosystems like Google and Amazon. I understand the need for a polished, scalable, and secure app like "SANGI." I will analyze, fix, and optimize the existing Flutter + Firebase app to ensure a fully functional, user-friendly platform. My approach involves structuring for simplicity, reliability, and long-term sustainability. I am ready to kick off this project. If this aligns with your project, feel free to reach out to discuss scope and pricing. Regards, Patrick

Hi there, AI-scaffolded Flutter apps come with predictable problems — broken imports, mismatched models, incomplete state management, and Firebase rules that leave the database wide open. We've cleaned up and completed exactly this type of project before. SANGI is essentially a hyperlocal service marketplace — we've built this category live and in production. What we bring: Codebase Fix & Architecture: - Full audit of existing project - Fix broken imports, router issues, model mismatches, build errors - Refactor to clean architecture + repository pattern - Provider/Riverpod state management implemented properly Core Features (all 11 modules): - Phone OTP auth, role-based access, session persistence - User + Provider system with verification flow - Service browsing, booking lifecycle, status management - Wallet system with Razorpay integration - Push notifications, ratings/reviews - GPS-based nearby services Admin Panel: - User/provider management, approval workflows - Service moderation, analytics, fraud prevention Branding & Launch: - Logo, app icon, splash screen, color theme - Signed AAB + Play Store ready assets + documentation Portfolio reference: Uplifters (client + freelancer service marketplace), Mohollla (hyperlocal multi-role ecosystem), JiffyJaf (booking + delivery platform) — all live on Play Store. Can you share the existing project repo or APK so we can assess current completion percentage before confirming scope and phasing?

@ApieTech

You've got a partially built Flutter + Firebase app that needs to reach production quality — that's exactly the kind of work we handle regularly. We've shipped similar multi-service marketplace apps with Firebase auth, Razorpay integration, GPS/location features, booking systems, and admin panels. Our approach: code audit first, fix broken modules, then complete each feature with clean state management and proper Firebase security rules. Timeline: 45 days for Play Store-ready submission. Ping me and we can review the codebase together.

Hi there, SANGI already has the right foundation, and what you need now is an experienced Flutter + Firebase developer who can transform the partially built project into a stable, scalable, production-ready ecosystem. I’ve worked on complex Flutter applications involving Firebase, payments, role-based systems, bookings, and marketplace workflows, so I understand the importance of clean architecture, performance, and long-term maintainability for a real-world app launch. My Solution approach: • Complete audit and cleanup of existing Flutter + Firebase architecture • Rebuild broken/incomplete modules using clean scalable structure • Optimize Firestore, authentication, wallet, booking, and notification flows • Prepare secure production-ready APK/AAB with deployment support • Is the current Firebase backend already structured with collections/rules, or does it also require a complete re-architecture? • Do you already have finalized UI/branding references for SANGI, or should the visual identity and UI kit be designed from scratch as part of the project? I’d be happy to review the current codebase, identify the critical gaps blocking production readiness, and help turn SANGI into a polished, scalable platform ready for Play Store launch.

Clean Architecture + Riverpod for scalable state management and separation of concerns Firebase (Auth, Firestore, Storage, Security Rules) set up properly with role-based access for Users, Providers, and Admins Razorpay payment flow with server-side verification — no client-side trust Modular feature structure — each module (Booking, Wallet, Reviews, Notifications) built independently so nothing breaks each other Full Firestore Security Rules — zero public access, proper role checks Push Notifications via FCM for booking updates and promotions GPS + location-aware service discovery (Google Maps ready) Hindi + English locale support baked in from the start Branding: I'll design a professional logo, app icon, splash screen, and a cohesive color system that feels local, trustworthy, and modern — fitting for a community platform. Deliverables: Full source code, working debug + release builds, Play Store–ready AAB, Firebase setup guide, Security Rules documentation, and Admin panel guide. Timeline estimate: 10–14 weeks for full production delivery, depending on the current state of your codebase (I'll give a precise timeline after the audit). I've shipped Flutter + Firebase apps to the Play Store and understand what "production-ready" actually means — proper error handling, no hardcoded keys, optimized Firestore reads, and smooth UX under real network conditions.
