Deploy MERN Stack app using Render, Vercel and mongoDB Atlas

Deploy a MERN Stack (MongoDB, Express, React, Node.js) application using modern cloud services. The React frontend is hosted on Vercel, the Node.js/Express backend runs on Render, and the database is managed with MongoDB Atlas. This setup creates a fully functional, scalable full-stack application accessible on the internet.
