Hello and welcome back—In this video I build and deploy a full stack social profile marketplace app using the PERN stack (PostgreSQL, Express, React, Node). The idea is simple: users can list their social media profiles for sale, other users can filter and browse listings, chat with the seller, and purchase the profile. I walk you through the full flow: homepage + marketplace with filters (platform, price, followers, verified/monetized), listing details page with gallery and metrics, user dashboard for “My Listings” and “My Orders”, plus real-time style messaging so buyers and sellers can talk before purchase. On the backend side, I connect everything with Neon (serverless Postgres) for users, listings, and orders. For auth and subscription billing I use Clerk, so I can offer a premium plan with a 7-day free trial (multiple listings + featured listings). I also add Stripe payments for checkout, an admin panel to verify and update credentials before a listing can be purchased, and Inngest to handle background jobs like sending listing/order emails and processing Clerk webhooks cleanly. Finally, I deploy the complete project on Vercel—this is the kind of live project you should add to your resume or even use as a solid college project.
