Web App Replication for WeChat & Alipay

I'm looking for a skilled developer to replicate my current web app for use in both WeChat and Alipay Miniapps. The existing web app is built in ReactJS and its key features include:

- 'Rent Battery' button
- Payment integration via WeChat Pay / Alipay
- User history tracking
- Location mapping via API (using JSON lat long)
- Feedback submission via camera or photos sent through API
- Authentication via Google and Apple ID (to be replaced with WeChat and Alipay ID)

The goal is to have users return with the same profile, which is crucial for this project. No new features are needed for the WeChat mini-app, just a straight replication of the current web app.

At this moment, I do not have the WeChat Mini Program developer account set up. If you have experience in this area and can assist, that would be a bonus.

Ideal skills and experience for this job include:
- Proficiency in ReactJS
- Prior experience with WeChat and Alipay Miniapp development
- Familiarity with API integration
- Experience in setting up WeChat Mini Program developer accounts
- Understanding of payment gateway integration
