Senior Expo/React Native Developer - iOS + Android Audio App, RevenueCat, TestFlight

We are looking for a senior React Native / Expo developer to build a polished iOS and Android consumer audio app. This is a private MVP. The full product concept, brand, content strategy, and commercial details will only be shared with shortlisted candidates after initial screening. The app is based on local audio playback, a simulated incoming call flow, multilingual content, synchronized text, and subscription monetization. No backend is required for V1. ## Required skills You must have strong experience with: * React Native * Expo * TypeScript * EAS Build / EAS Submit * iOS TestFlight delivery * Google Play internal testing * Local audio playback * JSON-driven content * RevenueCat subscriptions * Subscription paywalls * Basic analytics tracking * Arabic RTL layout support * Clean GitHub workflow * AI-assisted development tools such as Claude Code, Codex, Cursor, GitHub Copilot, ChatGPT, or similar AI tools are welcome and expected, but you remain fully responsible for architecture, code quality, debugging, testing, store builds, and final delivery. ## MVP scope The MVP includes: * onboarding flow * language selection * category / scenario selection * character / voice selection * simulated incoming call screen * quick call countdown * local audio playback * synchronized script text while audio plays * simple user controls * RevenueCat paywall * weekly / monthly / annual / lifetime products * local preference storage * Arabic RTL support * basic analytics events * iOS TestFlight build * Android internal testing build * final GitHub source code handoff ## Important notes * No backend in V1. * No user accounts in V1. * No AI features inside the app in V1. * Audio files will be local assets. * Scripts will be stored in JSON. * The app must be easy to extend later with more languages, audio packs, and content categories. * The code must be clean, simple, and maintainable. * Please do not propose an unnecessary backend, admin panel, database, or complex architecture. ## Delivery requirements Required deliverables: * GitHub repository * clean commits * EAS build configuration * iOS TestFlight builds * Android internal testing build * final source code handoff For iOS, TestFlight delivery is mandatory. Screenshots and simulator videos are not enough. We are looking for quality, reliability, and store-ready execution. ## Application questions Please answer all questions.
