Flutter Mobile App Developer -- 2

Looking for a flutter developer to help build our existing mobile app.
Skills: Flutter, Java, Google, firebase
Environment: IOS, Android
API experience: Google, Twilio, OTP, Stripe, Affirm/Pay later, Agora
Apps: Dating, Matching, Social, Events

If you are a flutter developer, please submit your previous apps for review.

We have a couple of items that need to be cleaned up on our mobile app for this proposal.
1. Onboarding user instance, data structure needs work and screens refinement on look. See attachment for clarity on onboarding users matching.

2. Payment with Strip, it is not working properly. Screens are set, the system is set, need to test transactions.

3. Matching(dating type of mating), the profile pairing, the logic is not working as designed, needs some fixes.

4. Matched users in chat or video chat created by another freelancer team here, not working as desired, need to be fixed.

5. Referral code injection at signup, need to implement.

There are other features we are looking to expand on. But once these items are updated, we will move on to cleaning up the rest and refining the relational database data structure.

Let me know what experience you have with firebase database and data structure setup in flutter/firebase, and your experience in data setup, API, authentication, and strip/apple/google pay.
