React Native App Enhancement & Upgrade

I need a React Native developer to upgrade my existing app from version 0.66 to 0.77 and then extend its functionality with 12-15 new screens. The app is a Woocommerce and WCFM-based platform.

Key Requirements:
- Upgrade the app to the latest stack
- Extend the backend API to accommodate new features including
Implementation of user authentication, payment processing, push notifications, shopping cart,
calculators, and paid referrals on the new screens.

The new screens will also require:
- A complete redesign, as opposed to simply matching the existing app's design.

Please note, a deep understanding and experience with Woocommerce and WCFM is crucial. The project can be accessed via the following repository: https://github.com/wsmm/WCFM.

Ideal Skills and Experience:
- Proficient in React Native
- Extensive experience with Woocommerce and WCFM
- Strong UI/UX skills for designing a new theme
- Backend API development expertise
- Experience with implementing features like user authentication and payment processing.
