Hi, I am very interested in your project to upgrade your existing Flutter Task Marketplace app. With my technical background in Computer and Network Engineering, I deeply understand system structures, API integrations, and secure data handling—which are critical for this major upgrade. Here is how I will approach and deliver your requirements: 1. System & State Management: Seamless integration with your existing codebase using Clean Architecture and SOLID principles, utilizing Provider, Riverpod, or BLoC as required. 2. Offline Support & Firebase Sync: Designing efficient offline caching logic using Firestore, ensuring Taskers can view cached tasks smoothly and data syncs perfectly once back online. 3. Advanced SDK Integrations: Implementing Google Maps API for Geolocation, Google ML Kit (OCR) for secure user verification, and biometric authentication for enhanced trust. 4. Communication & Escrow: Integrating Agora/Twilio for reliable in-app VoIP calls and refining your complex commission logic. 5. Deliverables: I will provide clean source code, fully updated APK/IPA for internal testing, and complete documentation on the new commission and verification rules. I have a reliable team ready to back up the mobile development frontend. Let's connect in the chat to review the existing source code and discuss the next steps! Best regards, Raditia Akbar

Hi there, I've shipped Flutter marketplace apps before the kind with maps, real-time task flows and backend logic that actually has to hold up under load. Your stack (Firebase, Clean Architecture, BLoC/Riverpod) is exactly what I work with day to day, so there's no ramp-up time here. What I'll deliver: ✅ New trust and safety modules wired into your existing codebase, no unnecessary rewrites ✅ OCR-based ID verification using Google ML Kit + biometric auth flow ✅ Commission and escrow logic rebuilt cleanly, with documentation explaining every rule and edge case ✅ In-app calling via Agora or Twilio, whichever fits your current setup ✅ Offline support for Taskers - cached task viewing with sync on reconnect ✅ Google Maps and geolocation updates where the current flow needs tightening ✅ Updated APK and IPA for internal testing, plus deployment-ready builds for both stores ✅ Clean, documented code following SOLID and Clean Architecture throughout Since this is a live app, I treat production stability as the first constraint, every module gets tested in isolation before touching the main flow. Just share the repo and I'll review the current architecture before we scope the first milestone. Looking forward to it!

Hi, I'm Vinod, a senior Flutter developer with 5+ years building and maintaining live marketplace and logistics apps on both stores. Working with existing codebases to add modules and refine logic is exactly the kind of work I do regularly. I've integrated Google Maps and Geolocation in delivery and task-based apps, implemented Google ML Kit for OCR-based verification flows, and built commission and escrow logic with Firebase Cloud Functions. For state management I'm comfortable with Riverpod and Bloc under Clean Architecture, and offline sync with Firestore caching is something I've handled in production. For this project I'll deliver the new trust and safety modules, refined commission logic, biometric or OCR-based verification, and VoIP calling integration — all added cleanly to your existing codebase without breaking what's already live. Updated APK and IPA for internal testing plus documentation on commission rules and verification flows will be included. A few questions to scope accurately: Is the current codebase using Riverpod or Bloc? Is Agora or Twilio already partially integrated, or starting fresh? How many new screens or flows are estimated for this upgrade? I can review your existing code before committing to a timeline. Let's discuss and move forward.

Hi, I can help upgrade your existing Flutter Task Marketplace app with a focus on Trust, Safety, Efficiency, and clean integration into the current codebase. I have experience with Flutter/Dart, Firebase Auth, Firestore, API integration, app deployment, and clean app architecture. I can work on new modules, improve UI/UX, refine commission logic, and add offline task caching/sync for Taskers. I am also comfortable working with Laravel/PHP and Kotlin Multiplatform, which helps me understand backend and cross-platform architecture better. For your requirements, I can assist with: * Flutter module development in the existing app * Firebase integration and Firestore logic updates * Commission and verification rule implementation * Offline cached task viewing with sync on reconnect * Google Maps / location-based task improvements * APK build for internal testing * Clear documentation for new logic and rules I will first review the current codebase, understand your existing flow, then implement the required modules without disturbing the live app structure. I am available to start immediately and can provide regular updates during development. Thanks.
