Imagine you have a team member that always criticises your work. You make commit after commit and put your best effort forth, you try to find the best names for variables and methods. You check your code using tools like RuboCop and Linters. Yet in every pull request, he asks you whether you considered refactoring objects. Things like extracting some logic out of a class, introducing view models and repository objects and sometimes even crazy stuff like domain driven design ideas. Why can't he leave you alone?
I tell you why: Because the fundamentals matter. They make the difference between software projects where things go smoothly and projects that just fail.
IT failures can also stunt economic growth and quality of life. Back in 1981, the U.S. Federal Aviation Administration began looking into upgrading its antiquated air-traffic-control system, but the effort to build a replacement soon became riddled with problems. By 1994, when the agency finally gave up on the project, the predicted cost had tripled, more than $2.6 billion had been spent, and the expected delivery date had slipped by several years. Every airplane passenger who is delayed because of gridlocked skyways still feels this cancellation; the cumulative economic impact of all those delays on just the U.S. airlines (never mind the passengers) approaches $50 billion.

That's $50 billion that could have been spent in another way. Now I cannot know what kinds of problems actually were present in this project. There are many different problems an IT project can suffer from. Projects of this size that fail, usually suffer from many of them at once.
Software development fundamentals are a big part. And these are a part you can control. So take every chance you get to improve at your craft. Here are some ideas for different skill levels.
For a junior/beginner:
For advanced / intermediates / professionals:
For seniors / experienced software engineers:
Linting your code and making sure the code meets minimum standards is one step. And it's a vital step. But the road is long and stony. (Sorry I had to write that 😇)
