Simple React JS Single-page Application

I'm looking for a developer to build a simple single-page application using React JS. The specifics of the design style are not set in stone as of yet, so a flexible approach would be beneficial. The application currently does not require user authentication, but the structure should allow for easy implementation in the future if needed.

Ideal skills and experience:
- Proficiency in React JS
- Experience in building single-page applications
- Flexibility in design and approach
- Forward-thinking, with the ability to anticipate future needs
