React + Java Authenticated Website

I need a complete website built with a React front-end and a Java back-end. Every visitor must be able to create an account, log in, and securely manage a session, so full user authentication is essential rather than just an admin-only gate. I’m flexible on the final feature set and visual style—we can refine the exact pages together—but the core stack is non-negotiable: React for the UI, Java (Spring Boot or a comparable framework) for the server, and a solid relational database behind it. Please structure the codebase for easy future expansion and hand over all source files, environment instructions, and a brief README that shows me how to run the project locally. Once the login, registration, password reset flow, and protected routes are operating smoothly, we’ll consider the first milestone complete.
