Instant Telegram Wallet Top-Up Integration

I am seeking a proficient developer to incorporate additional methods of adding funds to a Telegram wallet. These should include Credit Card, Debit Card, and Bank Transfer - offering users a diverse range of options to suit different preferences. The funds should be processed instantly, providing real-time updates to the wallet's balance.

For enhanced security, the system should integrate Two-factor Authentication (2FA), safeguarding the transactions of each user.

Ideal Skills:
- Expertise in payment gateway integration
- Knowledge in Telegram API
- Profound understanding of 2FA mechanisms
- Experience in developing secure digital wallet systems
