We are seeking an elite, senior-level Full-Stack Developerto engineer a high-velocity, real-time horse racing web platform from the ground up. The core application loop revolves around a fast-paced snake draft for individual horse races, complete with an integrated, synchronized sub-second live video stream of the race. Following official track results, the platform automatically executes structured financial payouts to users using Venmo/PayPal Payout rails. The entire tech stack must be built utilizing a unified all-JavaScript environment (MERN stack) optimized to eliminate database race conditions and handle volatile real-time traffic spikes. Core Key Milestones & Project Deliverables: Milestone 1: Backend Infrastructure & User Security (15%) Set up a Node.js/Express.js application environment and establish a scalable MongoDB Atlas architecture. Implement user registration, secure JWT/bcrypt authentication, profile management, and verified phone-number registration and/or email registration. Milestone 2: Sports Data Ingestion & Automation (25%) Establish integration with a third-party commercial horse racing API (e.g., Equibase or Sportradar). Build persistent background workers (using BullMQ, Redis, or Node-Cron) to automatically ingest daily race cards, scratches, gate changes, and final official race metrics. Milestone 3: Real-Time Draft & WebRTC Video Integration (40%) Develop an interactive React.js draft dashboard utilizing Socket.io for live, synchronized state management. Implement our custom mathematical snake draft logic featuring a strict 20-second user-pick countdown timer. Build server-side automatic timeout handlers to auto-assign choices if a user disconnects or freezes. Embed an ultra-low latency HTML5 video canvas layer leveraging WebRTC (via WHIP/WHEP protocols) to ingest an RTMP stream from a media server (e.g., Ant Media or Wowza) ensuring sub-500ms video playback. Milestone 4: Venmo Payout Integration & Compliance Guardrails (20%) Seamlessly integrate the official PayPal/Venmo Payouts API to programmatically distribute money from our platform wallet directly to users' accounts and/or phone numbers. This can be worked around using a p2p format, if necessary due to compliance and regulation. Code a reliable system ledger that deducts a custom platform percentage rake prior to finalizing winner distributions. Implement an IP geo-fencing gateway (such as MaxMind GeoIP2) to block real-money contest entry from illegal jurisdictions. Technical Stack Requirements: Frontend: React.js (Next.js preferred), Tailwind CSS, Socket.io-client. Backend: Node.js, Express.js, Socket.io, Node-Cron or BullMQ.Database & Memory: MongoDB (Mongoose), Redis (for lightning-fast leaderboard and timer caching). Streaming Protocols: WebRTC, WHIP/WHEP, RTMP stream handling. Integrations: PayPal/Venmo Payouts SDK, REST/JSON Sports Data APIs, GeoIP lookup utilities. Strict Operational Code Quality Terms: 1. Repository Ownership: All codebase code and architectural modules must be pushed to our private company GitHub repository at least three times a week. Milestone releases will only be approved after clean local compilation and inspection. 2. IP Assignment: By applying for and accepting this position, you acknowledge that 100% of the developed application logic, system schemas, and code components represent a dedicated Work-for-Hire owned exclusively by the client. 3. ACID Database Transactions: You must guarantee and demonstrate via unit testing that the MongoDB schema handles marketplace swaps and concurrent drafting selections via absolute ACID Transaction Sessions to totally prevent double-spend or double-draft race conditions. To Apply, Please Answer the Following 3 Screening Questions: 1. How do you plan to structure the server environment and React architecture to keep a 30-second live countdown timer perfectly synced down to the millisecond for 4 or more different players concurrently browsing via WebSockets? 2. Please share a summary or a live link of a project you built from scratch that handled live WebRTC ultra-low-latency video delivery or complex stream handshakes. 3. What is your specific experience with financial ledger architectures? Explain how you intend to protect the MongoDB operations against multi-user transactional conflicts.

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. 
