Good Software skills to be a good designer is a myth.
There is a misconception in the design industry that if you have excellent software skills. Then you are a good designer.
As per my experience in the UX industry, things are different because here you have to master your observation, user understanding, problem-solving skills, visualization, etc. You need to understand every node of knowledge to solve user problems. These are the thing that helps you to do better in UX.?
Good Software skills and an understanding of technology help you express your solution. So, as a UX person, you must be a skilled problem solver instead of a?skilled designer.
