Full-Stack Web Prototype for Venture-Backed Startup

A venture-backed startup needs a full-stack web prototype built ahead of its next funding round. The goal is a working demo that handles user accounts, a dashboard, and core business logic, all wrapped in a clean and responsive interface. The prototype will use React on the front end with a Node.js and Express backend, backed by PostgreSQL for data storage. We need basic authentication with email and social login options, role-based access for different user types, and a REST API that can support future mobile clients. The dashboard should pull sample data and present it in a way that is easy to read at a glance. Beyond the core build, we want the codebase set up in a way that makes future growth easy. That means a clear folder structure and basic test coverage on key functions. Docker will be used to keep environments consistent between local development and any future staging setup. We are looking for someone who can move fast without cutting corners, since this prototype will be shown to investors and early users to gauge interest. Clear updates on progress matter as much as the code itself, since timelines are tight and priorities may shift as we learn more from early feedback. If you have experience taking a product from a rough concept to something demoable, we would like to hear from you.
