I know a lot of engineers follow various principles like SOLID, DRY, Clean Architecture and so on, but as far as complexity goes it’s really rather straight forward. You never add abstractions until you can’t avoid them. We’ve had 20 years of these principles (and what other nonsense OOP had brought with it) now, and despite the fact that many of them were written by people who haven’t worked in software engineering since a decade before Python was made they still remain popular and largely unaltered. Which is silly considering our industry has never been more of a mess, with so many teams building complexity to “future proof” things that they will never need, to the point where some teams actively hinder the business.
Complexity is fairly straight forward in my opinion. You build after the YAGNI principles and you include things from SOLID, DRY, CLEAN, whatever when it makes sense to do so. If you happen to enter a team that has dug themselves into a pit of unnecessary complexity you need to work on reducing it.
This is takes a good engineer, because the fundamental reason to do this or that comes down to engineering. People who follow dogmas are not good engineers. You will even see the authors of some of these principles like Uncle Bob tell you that people who over complicate their code bases misunderstand his principles. Convenient when your career is selling consultant, but also very true.
