Headless WordPress to React Site

I am in need of a skilled developer who can convert my WordPress website into a React application. The website is fintech-related and currently serves as a headless WordPress site. I would like to transform it into a fully functional, responsive React web application. The end goal is to create a fast and dynamic user experience for my visitors.

Key requirements:
- Conversion of the existing WordPress site into a React application.
- Payment gateway integration (specifically Paystack)
- Ensuring the new React site is fully responsive across devices.

The ideal candidate should have experience in:
- Front-end development with React
- Integrating payment gateways, specifically Paystack
- Experience working with headless WordPress sites is a plus.
