[Question] How do I get my name to fill the first Google search result page?

I've been doing SEO on my own for a while now and haven't gotten any formal education as to the matter. I just want to test my skills using my name. It seems that I managed to rank everything I worked for but there's this one website that I can't get rid of. How do I manage to do that? I mean make every account that I made visible on Google's first search result page. Thank you in advance, friends.
