Nowhere in there do I see any reference to knowing about Version Control Software, such as GIT. Having a good handle on GIT allows you to take more risks, because you have a better set of options if they don't work out. That then gives you more freedom to refactor code.

As far as Object Oriented Programming, unless you're doing something as complex as a GUI builder, don't worry about making things object oriented if a simple record type will do the job.

It sounds like you're on the right track. Good luck!
