Too Long; Didn't Read
Having access to a more experienced programmer who wants to help you grow professionally can speed up your progress. You can ask your mentor to review your code while working on a personal project. Pay attention to the recommendations from your mentor, read and follow them. If you get feedback on the code review, at least engage with the proposition: discuss its pros and cons, even if there is no time to follow it. If you don’t have real-world problems from work, you can try creating some.
