Hello, I’m a mobile and full-stack developer with 10 years of experience building cross-platform applications using React Native, Android, iOS, REST APIs, secure authentication, and cloud deployment. For this project, I would recommend React Native as a maintainable single-codebase alternative that can integrate smoothly with your existing Python APIs, JWT authentication flow, staging environment, and current product architecture. I would recreate the key web features for mobile, implement secure token and session handling, connect Firebase Cloud Messaging for Android and iOS, and ensure responsive, native-like performance across devices. I would also support production builds, App Store and Google Play submission, and any review-related fixes required before launch. Let’s discuss the feature scope, API structure, and delivery milestones. Best regards

@javaidh390

Hi, I can help you to develop the app in native platforms (kotlin/Swift). I'm available for more discussion right now. Thanks!

With 8+ years of experience in mobile app development and adeptness in Flutter and React Native, I offer you the unique advantage of a seasoned professional who has traversed diverse industries such as healthcare, e-commerce, fintech, logistics and more whilst delivering high-performance, cross-platform applications. This background makes me perfectly positioned to cater to your Flutter iOS & Android App Build project. In addition to incorporating your existing authentication flow into the Flutter codebase, I ensure efficient integration of push notifications using Firebase Cloud Messaging (FCM) while your Python backend continues managing notification delivery. I can also ease your app deployment process by publishing the application to both Apple App Store and Google Play Store. Praising clarity in communication and providing timely project updates is my code of conduct which ensures smooth end-to-end project management. Having worked with databases like MySQL, MongoDB, Firebase - coupled with API integration skills utilizing my Python knowledge - you can rely on me for clean, well-structured, well-documented Flutter code implementing best practices for maintainability and scalability. Let's have a conversation about the development timeline, milestones and delivery plan soon!

Your Python backend will reject expired JWT tokens during API calls if the Flutter app doesn't implement silent refresh logic before the token expires. This will force users to re-login mid-session, which kills retention. Quick questions - are your Python APIs already handling refresh token rotation securely? And what's your target user base size so I can recommend the right FCM batching strategy? Here is the architectural approach: - FLUTTER: Build a stateful authentication wrapper that intercepts 401 responses and triggers token refresh before retrying failed requests, preventing session drops. - API INTEGRATION: Map all Python endpoints to a centralized Dio client with request/response interceptors for logging, error handling, and automatic retry logic. - PUSH NOTIFICATIONS: Implement FCM with topic-based subscriptions and background handlers that update local state even when the app is terminated, ensuring notifications don't get lost. I've built 4 production Flutter apps that scaled to 100K+ users across iOS and Android, including one fintech app that passed Apple's strict security review on the first submission. Let's schedule a 20-minute call to walk through your API contracts and confirm the deployment checklist before we kick off development.

Here is my portfolio: https://www.freelancer.in/u/ixorawebmob I’m interested in your project and would love to understand more details to ensure the best approach. Could you clarify: 1. Do you need this for mobile, web, or both? 2. Do you already have UI/UX designs or should we create them? 3. Will there be any third-party API or payment gateway integration? 4. What is your expected timeline for completion? 5. Are there any reference apps or websites you like?What specific features do you want to prioritize in the mobile app? Let’s discuss over chat! Regards, Arpit Jaiswal

@mehboobkatiyar

Hi, Since your backend, APIs, and designs are already in place, the focus is on delivering a clean, production-ready Flutter app that mirrors your web platform. I can integrate your existing JWT authentication, FCM push notifications, and Python APIs while following a scalable architecture that's easy to maintain. I’ll also assist with App Store and Google Play deployment until both apps are live. One question: does your current backend already support refresh tokens, or is that something we should implement? Best, Mehboob

Not only that, but I also have an extensive background in integrating push notifications using Firebase Cloud Messaging (FCM) - which seamlessly ties into your requirement for the Python backend to handle notification delivery.

@TechizeBuilder

Dear Client, I read "Flutter iOS & Android App Build" carefully and understand you want a single Flutter codebase that runs smoothly on both Android and iOS. My hands-on experience with Python, Mobile App Development, Android, iOS Development, Flutter, Android App Development aligns directly with what you need. I've shipped Flutter apps from scratch to store launch — clean architecture, smooth animations, native-feeling UI and solid API integrations — that stay easy to maintain as features grow. A few quick questions to get us started: 1. Do you need Android, iOS, or both from day one? 2. Are UI designs ready, or should I design the screens as well? 3. Is there an existing backend/API, or should I build that too? Thanks & Regards, Deepak
