RevenueCat Subscription + Paywall Integration for iOS & Android App (Expo/React Native)

I'm looking for a mobile developer who has shipped RevenueCat subscriptions in production, not someone who will figure it out on my dime. The project: iOS & Android app built with Expo (React Native). I need the full subscription flow wired up end-to-end: - App Store Connect setup: subscription group, monthly/annual products, free trial config, grace period - RevenueCat dashboard: products, entitlements, offerings, paywall setup - SDK integration in the app: purchase flow, entitlement checks, restore purchases - Paywall placement in the onboarding flow (post-onboarding, pre-content) - Purchase success moment done right — confirmation state, haptics/sound feedback, smooth transition into the app (the "cha-ching" moment matters to me) - Edge cases: failed purchases, subscription lapse, sandbox/StoreKit config testing - Backend entitlement sync so premium status is server-verified, not client-only How to apply (read carefully — this is the filter): Record a short Loom video walking me through your process: 1. A RevenueCat integration you've actually shipped — show me the paywall live in the app 2. How you'd structure the flow for my case: where the paywall sits, how you handle the trial → paid transition, and how you make the purchase moment feel good 3. Any gotchas you've hit with RevenueCat + Expo specifically (offerings cache, StoreKit testing, receipt validation, etc.) If your proposal does not include a Loom link, you will not be considered. No exceptions. Generic copy-paste proposals get archived immediately. The Loom is the application. Budget: Open to fixed price or hourly — quote based on your Loom walkthrough. Timeline: Ready to start immediately with the right person.
