Simple and busy Web3 game backend development

I am looking for a blockchain-powered game backend developer with a clear vision. But it's okay if you're not a blockchain developer. Now, This game already has a complete front-end and UI/UX, and with the help of a back-end developer, it will be ready soon. So I need the right person with enough experience and skills related to my project.

The issues that need to be addressed are:

- When a user submits a registration request, you must respond to it and send an "verified code" to the requesting email address.
- When a user clicks the "Charge" button, the game points should be claimed from their wallet account.
- The backend architecture needs to be changed. User addresses now contain multiple USDTs, and only the four addresses above are required.

I believe this is a very simple project and, with enough experience, could be completed in a short period of time. However, this is my first venture, and I'm interested in generating more revenue. So, I want to provide more value.

Because I have a new business idea, so if you complete my project perfectly, I'll suggest a new project that will generate more revenue.
