Expo Supabase Google Sign-In • $30 USD

Delivered exactly what was promised: native Google Sign-In with @react-native-google-signin/google-signin wired to Supabase via signInWithIdToken. Sessions persist correctly, secure logout is clean, and the integration was tested on iOS and Android. Code was clean, well-structured, and documented with clear setup notes so we could replicate the config. Communication was proactive and the work was finished on time. Would happily hire again.
