While it might be reasonable to assume by posting here you had done the fastai course, you don’t mention this, but that you’ve “only” done the theory - which doesn’t seem like something a fastai graduate would say.
So recommend your next step is to do https://course.fast.ai/, which operates the opposite of most courses by starting with practice and working back towards theory.
