rg111 has a good strategy here. For step 1, making a cats vs dogs classifier, the first lesson of the FastAI course will give you a path for doing this right away, and I wholeheartedly and enthusiastically recommend this course.

A sibling commenter mentions that certifications will do nothing for you. They're not exactly wrong, because what ultimately matters is that you can demonstrate your skills. Certifications and to a large extent even degrees mean very little; what matters is that you convince them you know how to do stuff. The best way to convince people you know how to do stuff is to be able to show a list of cool things you actually did. These courses and their certifications may not mean much on their own, but in the course of completing the courses you will develop skills and capabilities you can demonstrate and talk about in your resume and cover letter.
