I need a React Native developer to help complete and stabilize my social media app, QueFlic, before QA and beta launch. This is not a full rebuild. The app is already built, but it needs missing flows completed, smoother user experience, error handling, and final pre-QA fixes. The app is a social media platform with photo posts, video posts, Live Photo posts, music/location/tag overlays, WordBox polls/Q&A/reactions, comments, messaging, and sharing. Main work needed: 1. Error management Add clear signup/login errors for username already taken, email already used, wrong password, failed login, and network errors. Add upload and post creation error messages. If upload fails, user should see a retry option. If publishing fails, app should not create ghost posts. Permission errors for camera, photos, location, and music should show clear messages instead of crashing or silently failing. 2. Landing pages / overlay destinations Create or complete a music/sound page where users can see posts using the same song or sound. Create or complete a location page where users can see posts tagged at the same location. Make tagged users open their profile. Make WordBox open the correct poll, Q&A, or reaction page. Each page needs clean back navigation. 3. Smooth post creation flow User should be able to upload media, edit, add overlays, preview, publish, and return to the feed/timeline. User should not get stuck in editing screens. New posts should appear correctly after publishing. Basic delete post option should work for the post owner. 4. Live Photo flow Smooth the Live Photo feature so users can add photos into a video timeline, preview the final Live Photo, pause/play, go back to edit, and publish without freezing or getting stuck. 5. QF logo / watermark playback controls Tap QF logo once to pause video or Live Photo. Tap QF logo again to resume/play. Double tap QF logo to restart the video or Live Photo from the beginning. 6. Basic social actions Delete post. Comment on posts. Message option if already built. Share post using the phone’s native share sheet so users can share to Instagram, TikTok, YouTube, text message, or copy link. I want this handled as a fixed-price, milestone-based sprint. First milestone should be a code/app review and written fix plan. After that, we can move into implementation. Budget is $1,000–$1,500 depending on what can realistically be completed. I am looking for someone experienced with React Native, Firebase, media uploads, social app flows, iOS/TestFlight, and Android/Google Play testing. No full upfront payment.

Its suppose to be a lot easier to create and faster to implement. We are not techies and dont have the time to do this. Need someone to design and implement and manage the project. If you would go to Leapon.ai website, it does a good job of explaining providing instructions on how to do this. Once you have had a chance to review, please contact me with any questions and a price quote for your services. thank u

We're building a digital signage platform that runs across Android, webOS, and Tizen devices, and we need a senior Android engineer with real embedded/signage experience to help us level it up. Must-have: - Strong Android development in Kotlin - Experience building for digital signage, smart TV, streaming devices, kiosks, or similar embedded media platfroms - Comfort with concurrency, async, multithreading, and debugging race conditions and memory issues - Experience building for 24/7 device uptime Strong plus: - Experience with the signageos.io platform - Android SoC work (Amlogic, Rockchip, Qualcomm, MediaTek) - Media3 / ExoPlayer, hardware decoders, video playback pipelines webOS or Tizen - MDM / fleet management, MQTT - Performance tuning on constrained hardware The work: Media playback, device management, content delivery, and platform reliability across a fleet of long-running devices. This is device platform engineering, not mobile app development. If you've built signage or smart TV software at scale — especially on signageos.io — please mention it up front in your proposal.

The flagged item is the Apple reviewer email address in the submission section. Here's the corrected version with that removed: Job Posting — iOS React Native Engineer Needed (Critical Launch Crash) Title: React Native / iOS Engineer — Fix Launch-Blocking Crash Before App Store Submission Project: DuelDeck — real-money skill-based tournament card game, iOS app (React Native 0.84, New Architecture/Fabric enabled) Urgency: High — this is the single blocker preventing App Store submission. The problem The app crashes on every launch, within ~2 seconds, before any screen renders — including on a completely fresh install with no stored data. The crash signature is consistent and has been narrowed down through extensive isolation testing: An Objective-C exception is being thrown inside a TurboModule's synchronous/void method invocation (ObjCTurboModule::performVoidMethodInvocation), on the com.meta.react.turbomodulemanager.queue. Because this exception crosses a layer the New Architecture bridge cannot safely propagate, the entire process terminates (SIGABRT/abort()), regardless of any JavaScript-level error handling. What's already been ruled out (do not re-test these) Through direct binary-search isolation (disable component → clean rebuild → fresh install → measure time-to-crash), the following have been conclusively excluded as the cause: @react-native-community/geolocation PayPalCheckout SDK and our custom card payment native module A legacy unused Apple Pay native module Build architecture (tested both x86_64/Rosetta and native arm64 — same crash on both) react-native-mmkv (tested with MMKV fully bypassed, forced to AsyncStorage) What needs to happen Isolate the exact native module causing the crash. Strongest remaining candidates, in priority order: lottie-react-native, react-native-svg, react-native-screens, react-native-gesture-handler, a date/time picker library, an image picker library, a webview library. Use the same method: temporarily disable/remove one at a time, clean rebuild, fresh install (uninstall + reinstall to wipe all stored data), and confirm whether the crash persists. Fix the compatibility issue once found — typically a library version bump to one with confirmed New Architecture/Bridgeless support, or a patch to how the module is invoked. Verify a fully clean launch path: app must reach the splash screen, onboarding, and login screen reliably on a fresh install, every time, with no crash. How the app needs to function for this soft launch This is a soft launch, not the full feature set — the app needs to work cleanly within a deliberately narrowed scope. Once the crash is fixed, the build needs to behave exactly as follows before it's ready to submit: Onboarding and account creation. A new user goes through onboarding, then signs up with email and password only. No Google, Apple, or Facebook sign-in, and no phone/SMS login anywhere in the app — email is the only path in. After signup, the OTP email verification step has to actually work end to end: the code gets sent, the user enters it, and the account gets confirmed. No KYC gate. Users should be able to get into the main app and browse around without being forced through identity verification first. KYC stays in the backend for later, but it must not block access during this phase. Real location check. Geolocation needs to use actual Apple Core Location (device GPS with a proper permission prompt), not a workaround. This is what determines whether a user's state is eligible for real-money tournaments, and it needs to be a genuine native location check, not something hardcoded or guessed from the user's profile. Card deposits, no Apple Pay. Users fund their wallet with a debit or credit card through the PayPal card payment flow. Apple Pay should not appear as an option anywhere in this flow — card only. Tournament join has to work, fully. A user with money in their wallet needs to be able to open a tournament, pay the entry fee out of their balance, and get confirmed as entered — the whole payment-to-confirmed-entry path needs to be solid, not just the deposit step in isolation. VS / free play is off. The Invite tab and any 1-on-1 free-play matchmaking should not be live for this launch — show a "coming soon" placeholder instead of the real flow. Withdraw stays disabled. The withdraw button should be visibly present but greyed out / non-functional for now. Deposited funds are playable only and not withdrawable during this phase. Audio is off, and that's fine for now. Background music and sound effects are intentionally disabled for this launch and are not part of what's required to ship — don't spend time trying to bring them back unless explicitly asked. Everything else stays as is. Rankings, profile, avatar upload, live countdown timers on tournament cards, and the rest of the existing feature set should continue working exactly as they do now — the engineer's job is the crash fix and the items above, not a feature audit of the whole app. Admin dashboard. Tournament creation, editing, and cancellation from the admin dashboard need to be reliable, since tournaments will be set up and managed from there around the time of launch. Re-validate the full soft-launch feature set above after the crash fix — confirming each item works on a real build, not just in theory. Prepare and submit the TestFlight build for internal testing, then prepare the App Store Connect submission (screenshots, privacy details, review notes). A pre-configured Apple reviewer test account will be provided once hired. Requirements Strong hands-on experience with React Native's New Architecture (Fabric, TurboModules, Bridgeless mode) specifically — this is not a general React Native bug, it requires someone comfortable reading Objective-C++/Swift native module bridging code and Xcode crash reports (.ips files). Comfortable working directly with .ips crash logs, symbolicating stack traces, and reasoning about ObjC exception propagation across the JSI/TurboModule boundary. Experience shipping React Native apps through TestFlight and App Store review. Familiarity with CocoaPods, Xcode build configurations, and debugging native module linkage issues. Codebase context React Native 0.84.1, iOS min target 15.1, New Architecture enabled. Backend already live and stable (Node.js/PostgreSQL on AWS ECS) — this is an iOS-app-only fix. Full crash investigation notes (stack traces, what's been tested, environment details) will be provided to the selected candidate at project start so no time is wasted repeating already-completed diagnostic work. Communication and file sharing will happen entirely through the platform's built-in tools. 

We need someone who is an expert in Flutter, Firebase, Stripe, to create a Progressive Wed App from an app that has been approved for Android but not yet approved for IOS. The app has already been built, we need an expert to now create a web app version, add the link to the website, handle the Stripe integration for a subscription model. Once this is complete there is a chance to remain on the team to update the app as needed and handle updates. As the app was built in Flutter this should nto take long at all to convert to a web app.
