Loaded question on a plugin idea website like you need a budget

How to design a website that a user/member would be able to budget make different categories, enter their paycheck and budget their money. The user would be able to track expenses/spending that would subtract what they budgeted. Create a saving goal amount. Create a debt free plan seeing debt going down. I created something similar to what I want to do in numbers but not sure how to design in a website. What should I learn or what can I do to make this project work.

well, that’s rather broad…

it will require: at least a framework, solid backend knowledge, and security knowledge. A server (space where to store user datas). Other stuff…

Have you done the various certifications on freecodecamp? that’s all stuff you will need to be comfortable with (or equivalents, like a different framework or a different back-end language).

do you also want the companion mobile apps? that’s other things to learn.
