I’d keep this compliant because they clearly say no official API exists. Hi — Elias here from Miami. I can help with the Flutter Android build, but I need to be clear that without official or approved API access, I would not recommend reverse-engineering private delivery platform APIs or handling driver credentials in a way that could violate platform terms or create account/security risk. A safer approach is to build the app around compliant integrations where API access is authorized, with secure login, encrypted token storage, background services, FCM notifications, configurable filters, and a modular API layer that can be maintained long-term. If partner/API access becomes available, the same Flutter architecture can support real-time offer streaming through WebSocket/gRPC cleanly. I’ve worked on Flutter apps involving secure auth, background services, push notifications, real-time APIs, and long-term integration maintenance. Q1 – Do you have written permission or partner access for any target platform? Q2 – Would you consider a compliant MVP focused on driver workflow, notifications, and manual decision support first? Q3 – Should Sprint 1 focus on the Flutter architecture and approved API-ready integration layer? Happy to help structure a safe, maintainable Sprint 1 plan. Looking forward to hearing from you.

Hello there, I will build your Flutter delivery app — login flow, WebSocket/gRPC offer streaming, background foreground service, and FCM push notifications — all running on non-rooted Android 8.0+. For background execution, I will use a persistent foreground service with a sticky notification to prevent Android from killing the process during offer listening. Questions: 1) Is the delivery platform API documented, or will reverse-engineering the token flow be required? 2) What auto-accept rules do drivers need — payout threshold, max distance, or both? This bid is an initial estimate — I will confirm the final cost and timeline once we have walked through the complete requirements together. Looking forward to your response. Best regards, Kamran

@ergauravsethi376

Hi, I have 9+ years of development experience and strong hands-on expertise in Flutter, Dart, and building real-time, API-driven mobile applications. Your requirement for a background-running Android app with direct API integration, WebSocket streaming, and automated decision logic aligns closely with my experience. For this project, my approach would be: Analyze and reverse-engineer the delivery platform’s API flow (authentication, token lifecycle, endpoints). Implement secure login and session handling using encrypted storage. Set up real-time offer streaming via WebSocket/gRPC. Build a reliable background service (foreground service for Android) to receive offers even when the app is closed. Integrate FCM for instant notifications with relevant offer details. Develop rule-based logic for auto-accept/reject with configurable filters. Ensure the app runs smoothly on non-rooted devices (API 26+), without relying on screen automation. I have experience working with: Dio / REST APIs and real-time communication Background services and performance optimization Secure storage and authentication systems Scalable app architecture for long-term maintenance I understand the complexity of maintaining such apps when APIs change, and I will document endpoints, token flow, and provide clear guidance for future updates. Let’s schedule a quick 10-minute call so I can fully understand your requirements. After that, I’ll share an accurate cost and timeline. Thanks! Gaurav

@OscarMozo

Hi, I can help you You want an Android app for drivers that logs in once, listens to live offers, sends clear alerts, and auto-accepts or rejects based on simple rules, all while running quietly in the background on normal phones. It should install easily, show real offers, and include code, a short demo, and simple notes on how to keep it working. This will take a few days, I've been doing this type of work for years. I have short walkthrough videos on my Freelancer profile showing similar work. 1) Do you already have API docs or a test account for the target platform? 2) What exact rules and final notification layout do you want for offers? Ideally, we have a call and go through the details together so I can make sure I understand everything correctly, address any questions, and give you a quote and timeline. Would that work? Best, Nicolas

@danielboggs

Hello, I can help diagnose and fix the homepage issues quickly and properly. From your description, the priority is not just patching individual problems, but identifying the root causes of both the functionality issues and the performance bottlenecks so the homepage remains stable after the fixes are applied. I have experience troubleshooting HTML, CSS, JavaScript, frontend performance issues, Core Web Vitals optimization, asset optimization, caching strategies, and browser compatibility problems. I've worked on projects involving broken UI interactions, JavaScript errors, slow-loading pages, render-blocking resources, and mobile performance improvements. My approach would be to first review the reported issues, inspect the homepage using browser diagnostics and performance tools, fix the functionality problems, optimize scripts and assets, verify Core Web Vitals improvements, and then provide a clear summary of everything that was changed. Once you send the task list, I can review it and provide a realistic timeline for completing the fixes. Best regards,
Daniel
