Learning django for my startup, suggestions on tech stack to learn

Hello Peeps,

I used to work in python only for data though. Currently learning django to help me write the code for my idea.

I'm working on an idea that would mostly be a web app.

Users can perform actions on the webpage. Imagine interacting with screens and they would just be images, I'd write the other custom logics.

Any recommendations for the tech stack I should learn?
