Hello and welcome back to another exciting tutorial of GreatStack. In this video, I build and deploy a full stack project management application using the PERN stack (PostgreSQL, Express, React, Node). I start by showing you the complete demo: users can sign up, create an organization/workspace, switch between multiple organizations, invite members, create projects, and then create tasks inside projects with status, priority, type, and due dates. You also get a clean dashboard with project overview cards, task summary, recent activity, plus project pages with task list, calendar, analytics, and settings—along with a beautiful light/dark mode. After the walkthrough, I take you step-by-step from a ready open-source React + Tailwind template to a fully functional app. I integrate Clerk for authentication and organization management (sign in/sign up, user button, org creation, invitations), then I start building the backend with Express (basic server setup, CORS, JSON middleware, nodemon). For the database, I use Neon PostgreSQL to store users, organizations, members, projects, and tasks. And for background jobs like task assignment emails, due-date reminder emails, and handling Clerk webhooks efficiently, I use Inngest. Finally, I deploy the project online using Vercel so you can add the live link to your resume or use it as a college project.
