Finalize and Deploy Cross-Platform Mobile App

@thesurya9

I can help finalize your cross-platform mobile app. With 3+ years of experience in React Native and Flutter, I’ve published apps on both the Google Play Store and Apple App Store. I’ll handle testing (unit/integration), bug fixes, performance optimization, and complete deployment including code signing and store submission. I’m ready to start within a week, take full ownership of the final steps, and provide daily sync updates until launch. Links to my live apps can be shared to demonstrate relevant experience.

Hi, I can step in and take your existing Flutter/React Native app to full production readiness, focusing on testing, stability, performance, and smooth App Store + Play Store deployment. Since your UI and backend are already complete, I’ll primarily work on the “last-mile engineering” to make sure the app is stable, fast, and fully compliant for release. What I will handle: • Full QA testing (manual + automated where needed) • Bug fixing and performance optimization • API & WebSocket stability checks • Push notification validation (FCM/APNs) • App signing, versioning, and release builds (APK + IPA) • Google Play Store & Apple App Store submission end-to-end • Store listing setup and compliance checks Delivery focus: • Clean, stable production build on both platforms • Zero critical bugs in release flow • Smooth login, API, and notification workflows • Successfully published apps or “Ready for Review” status I have worked on multiple production app launches involving store submission, certificate handling, and release debugging, so I’m comfortable owning the final delivery phase without hand-holding. I can start immediately and ensure a smooth, reliable release process for both Android and iOS

Hi, The final stage of an app is often the most critical. Getting it production-ready requires thorough testing, fixing edge-case bugs, optimizing performance, and ensuring a smooth App Store and Play Store submission. That's exactly where I can help. From your requirements, I understand the UI and backend are already in place, and you're looking for someone to take ownership of the final phase—testing the application, resolving bugs, optimizing performance, validating API and WebSocket integrations, preparing production builds, and handling deployment to both app stores. My approach is to begin with a thorough code review, identify stability and performance issues, execute unit and integration testing where applicable, resolve deployment blockers, and prepare the app for a successful release. I follow clean, modular coding practices, work efficiently with Git, and believe in proactive communication with regular progress updates. I can start within your required timeline and am comfortable with daily sync calls throughout the project. I can also share links to my published mobile applications and relevant React Native/Flutter projects. A couple of quick questions: • Is the app built with React Native (Expo/CLI) or Flutter? • Are your Apple Developer and Google Play Console accounts already configured for production releases? I'd love to help take your app across the finish line and ensure a smooth launch on both platforms. Looking forward to hearing from you!

Over the past 10 years, I've successfully completed over 100 projects, with a focus on website development, mobile apps, and API integrations. Boasting 3+ years in mobile app development using React Native and having two of my applications already live on both major platforms (Google Play Store and Apple App Store), I am confident that I can handle your project with ease. Apart from building the app UI and backend, you specifically require someone who can handle the final mile which includes rigorous testing, bug squashing, speed optimization and successful publishing; these are areas in which I put strong emphasis. My experience is not limited to just building and launching - my proficiency extends to managing code signing certificates, handling complete app store submission processes, as well as writing and executing unit tests and integration tests. Combining these aspects with comprehensive knowledge of RESTful APIs, WebSockets, performance optimization techniques, Git-based workflow I emphasize on clean coding practices mean that your app will be robust, efficient and scalable for years to come. With me in charge of your project you will receive timely updates through daily sync calls ensuring tight collaboration toward completion. Excited to start!

Last-mile deploys usually get stuck either on app store policies or subtle state bugs that show up after beta, not during dev cycles. I ship both Flutter and React Native apps to Play Store and App Store—eSignatory and CawGo are live now (search "eSignatory" or "CawGo" on both stores). I'll run full integration and UI tests (Jest, Detox, Flutter test), optimize for launch time and performance, and handle certs, code signing, and store listing. Have dealt with ATS, ATT, push (FCM/APNs), and all the usual review blockers. Used REST and WebSocket APIs on every shipping app. If you need marketplace/booking logic checked, worked on multi-role platforms like Live Connect (NDA). Can start within days—just send your Git repo and any pending store accounts, and I’ll begin by validating app store readiness. Pradeep

@ahmadraza001912

Hi, App UI and backend already built — you're at the finish line and just need someone to get it past App Store review and Play Store submission without introducing regressions. I've handled this exact last-mile: production-grade APK/IPA builds, code signing certificates, and the full store submission process including metadata, screenshots, and responding to reviewer rejections. For a cross-platform app, my approach here would be: - Flutter or React Native (CLI) depending on the existing codebase - Jest + Detox for unit tests and integration tests - FCM / APNs for push notifications if not wired yet - Git branching to isolate fixes from the release build I'm comfortable doing daily sync calls and can start within the week. One question: is the existing codebase React Native (Expo or CLI) or Flutter? That'll tell me immediately how the code signing setup is structured and what the store submission flow looks like. — Ahmad
