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.

This is a Flutterflow app called CARS which stands for Cybersecurity Awareness & Resilience Solution. I am a Phd student at NSU and I will be engaging in developmental research for microbusiness owners testing cyber awareness and resilience for their microbusinesses. This is intentionally a minimal research app. There is no backend all logic is handled in FlutterFlow + Firestore. The app enforces sequential viewing of videos and tracks completion and rewatch behavior only. The focus is on simplicity, reliability, and clean UX. Avoid over-engineering. There are 102 videos that have already been loaded via csv via Rowy into Firebase/Firestore. You already have: videoId title module order videoUrl and the videos are set-up to play sequentially one after another. If you get the job, I will provide the csv with placeholders for videourl for privacy. Please review the attached Developer Brief to get an idea of the specifics of this job. Thank you.

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 are a small, funded product team taking a live iOS and Android app (React Native) into its most important release. The app is moving from a manual tool to an intelligent, automated daily companion. We are hiring one senior developer to own both the front-end experience and the back-end intelligence layer, and to help us make the key architecture decisions for what comes next. Full product details are shared under NDA. This post is about the bar we need you to clear, so read the application instructions carefully. The One Thing That Matters Most You have personally built and shipped cross-platform mobile apps that real users have in their hands today. Not prototypes, not tutorials, not apps that stalled before launch. We want to see them, use them, and hear exactly what you built. Everything below matters, but nothing matters more than proof that you have taken a mobile app all the way to the App Store and Google Play and kept it running. What You Will Own Front end A polished, animated experience: onboarding flows, sequenced screens, and a completion moment that has to feel premium. We care about craft and detail, not just functional screens. Back end Data modeling, serverless functions, a per-user scheduled notification engine, third-party AI API integration, subscription entitlement logic, and a time-series scoring system. Our current stack runs on Firebase, so you will work in it from day one, but part of your job is to tell us where it should go next. Your first deliverables In your first 1-2 weeks, before heavy building starts, you will: Review our functional spec (FSD) and write the technical spec (TSD) for how you will build it Give us your own build estimate and milestone plan against the October 31, 2026 target. Deliver a written backend recommendation: stay on our current stack, extend it, or migrate. For the backend call, weigh Firebase/Firestore, Postgres (for example Supabase), and other options against our real needs: 10,000+ active users, AI API integration, offline-first sync, reliable push at scale, velocity, and cost. We want an objective read from someone who has shipped on more than one backend, not someone married to a single tool. What You Must Have 3+ years building React Native apps that are live in production on both iOS and Android. Shipped and maintained, not just started. Strong full-stack backend fundamentals: serverless/cloud functions, data modeling, auth, security rules or access control, and API design. Hands-on experience with both a NoSQL database (for example Firestore) and a relational database (Postgres or similar). You should be able to reason about the trade-offs, because you will be advising us on exactly that. Production experience integrating a third-party AI API (Claude, OpenAI, or comparable), including handling latency, cost, and structured output. Proficient in TypeScript. Our codebase is TypeScript. RevenueCat for subscription entitlement management. It is already integrated in our codebase. Push notification infrastructure and scheduled/triggered server logic that runs reliably per user. Clear written English and comfort working async-first over Slack, with GitHub-based code review. Strong Advantage (Not Required) If you have shipped these before, tell us. If not, we expect a strong engineer to pick them up quickly. Firebase at real scale in production: Firestore schema design, Cloud Functions with complex triggers, FCM, and Firebase Auth. UX/UI craft: polished animation work such as SVG stroke animation, radial gradients, and staggered/sequenced motion. Device-native speech-to-text on iOS and Android. Anthropic Claude API specifics: prompt caching, system-prompt engineering, structured output. Experience scaling a consumer or wellness/subscription app to 10,000+ active users. Engagement Time commitment: we expect roughly 20+ hours per week, sustained. This is a real ongoing engagement, not a few hours here and there. Timeline: our v3 release targets October 2026. Expect focused, steady delivery between now and then, with the backend recommendation done in your first few weeks so we can lock the architecture early. Scope: substantial multi-month build with strong potential to continue into v3+ if it is a good fit. We would rather find one reliable partner for the long haul than churn through contractors. Tooling: GitHub, Slack for daily communication, TestFlight for iOS builds. Contract, hourly or fixed-price per sprint. Your preference. Tell us your rate and preferred structure. All builds, schema changes, and deployments are reviewed before release. We commit to a 48-hour feedback turnaround. How to Apply — Read Carefully You must submit a portfolio website or a link to your work before any screening call. Applications without a portfolio link will not be reviewed and will not receive a call. To be considered, include all of the following: A portfolio or work link (required, no exceptions). Applications without one will not be reviewed. One shipped mobile app you are proud of, live on iOS and/or Android, with a store link or video. Tell us specifically what you built. One backend system or serverless function you built. Describe the scale, the data model, and the hardest problem you solved. One example of UI craft or complex interaction, with the visible result (link, video, or GIF). Your one-paragraph read on the backend question: given the needs above, would you stay, extend, or migrate, and why? A confident “it depends, here is how I would decide” is a great answer. A brief note on how you approach scoping and estimating a build like this. We do not expect a number before you have seen the spec, but we want to see how you think about it. Your rate, preferred engagement structure, and realistic start date. How many hours per week you can realistically commit, sustained, between now and an October 31, 2026 v3 target. Be honest. We would rather know your real capacity up front. We respond to every complete application. We are looking for a developer who takes their craft seriously.
