I am looking for a skilled developer to create an app that will facilitate payments by automatically converting fiat in the sender's wallet to USDT, transferring it to a recipient, and then converting it back to fiat in the recipient's wallet. The app needs to be developed for both iOS and Android platforms.

API(s) for Currency Conversion and Transfer:
- I do not have the necessary API(s) for currency conversion and transfer. The developer will need to create this functionality within the app.

Ideal Skills and Experience:
- Experience in developing mobile apps for both iOS and Android platforms.
- Knowledge and expertise in currency conversion and transfer.
- Ability to create and implement APIs for currency conversion and transfer.
- Strong problem-solving skills and attention to detail.
