We are looking for an experienced developer or small team to fix three important issues and demonstrate their ability before discussing a longer-term engagement.

Ensure location services work consistently on Android and iOS. Issue 2: Authentication & User Experience Review OTP/login process. Improve reliability of user sign-in. Reduce friction during onboarding. We are considering allowing users to start exploring before requiring registration.
