Hi Muxe! I'm always excited to hear about another woman interested in entering the STEM field. The best answer I can give you is to stay in school! Even if you already have the technical chops to engineer around the best software maven you know, you have to be able to prove it on paper. And that usually means getting a BS. I'd highly advocate for a Computer Science, Marketing or Software Engineering degree. Go into it focused on your end goal (computer engineering) and you'll come out the other side with a ton of useful skills.
I know I am answering bit late here, but you know you can become what you want to be in future it's not hard only thing you need to have is commitment and hardwork or I would say softwork now a days
To answer your question, To become a computer engineer all you need to do is take up a Bachelor Degree in Science or Bachelor of Engineering in Computer Engineering or Information technology.
Computer Engineers has lot of potential in future as the world is now revolving around computers, studying about computers or software is the safest and brightest decision for the future. I would recommend you to go through the following the articles of list of Computer engineering degrees I found in South Africa, I am not from South Africa but I would say any country the Computer and the Education for it won't change.
