"Hey Arturo, question...in creating the personal brand...do I have to stick with my name or can a pseudonym be used? So that there is like a professional presence and the personal brand presence? Or should it just the personal one linked to the business?"
Solution:
Good question, I'd personally combine the two if possible but by your name on Instagram use your actual name followed by keywords related to your niche and if you're using the pseudonym or a combination of both that and name then that can be in the username (the @ handle). You can check out
