Node.js to React.js Conversion -- 2

I have a small Node.js application focused on user interaction that I would like to convert into a React.js application. A deep understanding of React.js and Node.js is necessary. The new application should reuse the existing design of the Node.js application. Hence, familiarity with UI/UX principles will be beneficial. Your task will include:

- Creating a fully interactive React.js application.
- Reusing the existing design for the new application.

Ideal candidates should have extensive experience in React.js, Node.js, and UI/UX design principles.
