Ask HN: How much effort do you put into the code quality of your side projects

I'd like to know what you have to say about the topic of code quality in personal side projects. Be it from your experience in maintaining your own, or looking at other people's code.

Considering the fact you publicly display all of your work and use it in building your career, when is it considered acceptable to leave the project in its MVP state, and when is it more appropriate to build it up to a standard?
