Simple multi user software stack

so I've been developing web apps for a few years now, but have never created an entire application on my own.

Now I want to create a simple multi-user web app with simple crud operations. My question now is: What is the easiest feasible software stack to use for my use-case?

First of all I want to develop a backend, the frontend can wait for now.

My current thoughts were the following: Backend-Framework: Express.js Multi-User: Auth.js ORM: Prisma (maybe not required)

Database: MySQL

Later on: Frontend Framework: React Native (for mobile + web application)

(Also using typescript, I understand most of the parts of this project, mostly wondering about the deployment and the multi-user part)

I'll just be hosting the server on some cheap rental server.

Thanks for your help in advance.

I already tried some approaches and ended up on said software stack for backend use.
