Your advice is completely un-actionable. "Learn the gestalt?" Do you mean the principles of gestalt design? Because half of those are entirely about designing clever logos, not about making useful UX. If designers spent less time gooning over the FedEx logo, everyone would be better off. The remaining principles are good to understand, but all the challenge is in applying them for specific cases.
Or do you mean: simply understand all of human psychology and design UIs that work for everyone? That seems to be what you're saying, but both are impossible. Nobody really understands human psychology, especially those who think they do. Show me a psychology finding that is applicable to UI design and I'll show you a study of 30 college freshman that doesn't replicate. And you cannot design a UI that is intuitive for everyone; people are too different, and the "average person" literally doesn't exist.
So what exactly is your advice? Know everything and apply that knowledge appropriately for your specific situation? React and Kubernetes have clear documentation, tutorials, and canonical ways of doing things. UX design has a couple of clever books. The analogue of "just learn good UX design" is not "just learn React", it's "just learn how to write readable, maintainable, clear, performant code everywhere." It takes decades.
