Playfab backend with Amazon Ses and Stripe attached to form = a global gift card system

I'm in need of a Playfab backend developer who can perfectly integrate Amazon AWS, SES, and Stripe to form a global gift card system.
A production quality, enterprise global gift card system.
Powered by a form that is easy to connect to by domain, that has a form builder attached to the playfab backend powering our one big game (a big grand exchange of gift cards).
The company signs up, uploads product photos and their logo then gets an automated storefront form created with their own items ready for sale to customers and to play in mini games.
They then sign up their domain with us through Amazon ses to have automated email sending through the form. It's basically an email newsletter collector form that runs as a game via the playfab backend. Deployed on AWS/Azure/GCP, any of the 3 work with global availability.
I appreciate your work on this.

You will be tasked with handling:

- User authentication
- Gift card management
- Payment processing
- Domain signup through Amazon AWS

Furthermore, your expertise in creating simple minigames would be greatly appreciated.

As for the gift card management system, it should offer:

- The ability to add/remove funds
- Generate new gift cards
- Track gift card usage

Other significant functionalities would be:

- Setting up player collaboration (minigames)
- Implementing email notifications and transactional emails
- Designing customer email funnel
- Integrating Stripe for payments
- Analyzing and reporting
- Ensuring security and performance
- Testing and deployment
- Providing documentation and support

Ideal candidates should have extensive experience in Playfab backend development, knowledge of cloud platforms especially Amazon AWS, and have handled similar projects
