Sports Fantasy App Payment Gateway Integration

I'm seeking a skilled developer who can integrate a payment gateway into my sports fantasy application swiftly. The payment gateway should support:

- Familiarity with Credit/Debit Cards, Digital Wallets, and Bank Transfers
- Previous experience with sports fantasy applications is a plus
- Strong understanding of user experience in payment processes.
