Does the software design mean only mean to make modular, reusable, and abstracted code ? or there is other things to care about ?

Hello everyone, I'm new  here, I'm working on  graduation project, which is a  simple, fullstack web app  ;  frontend, backend, and I also use some AI framework (LangGraph specifically).

even though  the project is relatively simple,  I don't  just want to ' make  code that works' , but I want to make  ' maintainable, scalable code', because I value code clarity and reusability  so that it will need minimal effort for anyone else to read and understand it, but I wonder is that the only things I must care about ? is that what software design principles or standards  only care about ? .

 

I  just heard about this book,  does this book contain answers to such questions ?
