metanochava/back ? reverse-engineered prompt

Build me the backend for a small SaaS app called Mytech SaaS.

I want a working Python web app that can handle the main business areas already hinted at in the project, like sales, inventory, HR, pharmacy, and healthcare. Set it up so I can create, view, update, and track records in each area, with a clean admin style interface and sensible defaults. It should be easy to run locally, easy to extend later, and organized in a way that keeps each business area separate but connected where needed.

Please make sure there’s a solid foundation for things like user access, basic data validation, and simple reporting or dashboards if that fits naturally. If you need to check current docs or best practices for anything, go ahead and look them up online.

Also make sure the project starts cleanly from the main entry point, includes whatever setup is needed for development, and doesn’t leave me with broken or placeholder parts where core functionality should be.
