docker – Student notes sharing and chatting/discussions platform with Raspberry Pi 4 4GB RAM as the server

I hope you’re doing well! I’m a student and I recently got an idea to build a website that is used to upload student’s notes and previous year question papers, and it also includes chatting and like discussions. The stack I’d like to use is React or Next.js for the frontend, Node.js + Express.js for the backend, Socket.IO for real-time chat, PostgreSQL for database, external SSD attached to Raspberry Pi for file storage, and Nginx used for reverse proxy. JWT tokens for Auth and Docker for deployment

And the important part, I want to host this website on the Raspberry Pi. I want to use the Raspberry Pi 4 4GB RAM as the server

Any suggestions please drop it down!

Thankyou!!
