I have a React Native application built with Expo. The app is already working, and I am NOT looking for feature development or coding. What I need: - Someone experienced with Expo + EAS Build - Generate production builds for: • iOS (TestFlight) • Android (Google Play – AAB) - Handle signing, certificates, provisioning profiles - Configure app.json / eas.json if needed - Upload the builds to: • App Store Connect (TestFlight) • Google Play Console - Ensure the app is ready for store review (basic checks) Tech stack: - React Native (Expo) - EAS Build - Supabase backend Requirements: - Proven experience publishing Expo apps - Must have published apps on BOTH App Store and Google Play before - Clear communication (I’m not a developer) Deliverables: - App visible in TestFlight - App uploaded to Google Play Console (Internal testing or Production) - Short documentation of what was done Timeline: - 1–3 days maximum Important: This is a publishing & deployment task ONLY. No UI, no backend, no feature development.
