I’m putting together a multi-page web application built with ReactJS (NextJS framework), and I’d like a hand finishing the core functionality. The app must: • include secure user authentication (sign-up, login, protected routes) • render dynamic content pulled from a NoSQL database (MongoDB is my current pick, but I’m open to another option like Firebase) • handle multiple forms with client- and server-side validation All pages are already wireframed; your job is to implement the React/Next components, integrate the database layer, and ensure the UX remains smooth across page transitions. I’ll provide Figma mock-ups, the existing repo, and API endpoints on project start. Acceptance criteria 1. Users can register, verify, log in/out, ...
