Not sure your exact situation, but from just the information you shared, there seem to be three options that you can choose from.
remain undiscovered: just do nothing, stay where you are
heavily curate your profile: get rid of the stuff you want to hide which I presume would be the reason you want to stay anonymous
just show everything: hide nothing, let them judge you
There’s actually the fourth option in which you create something new just to show them, but would it be the kind of piece you’d be proud of? It wouldn’t be the same as the ones you’d want to show them.
