Getting into the workplace

Getting into the workplace


Hi! So I am 17 and about to get my responsive web design certificate. I’m interested in getting into freelance
work but I am pretty sure I don’t have enough knowledge. I also intend to get a more stable job later on but since i’m 17 I need to wait till i’m 18 I assume. I also know I want to be a full stack developer (hopefully). So number one, should I just wait till I get all the certifications? And two, What if not all of the certifications should I focus on first.
I have a sudo-portfolio here on codepen.

Any advice is welcome! Also quick note, I have a G.E.D already and I am done with high school. I also intend to use freecodecamp as my programming education(aka I am not attending a college).
