Introducing myself with my nickname - memorable or unprofessional?

[Aaron Mikottis]

Hey guys I wanted to run an idea by you all really quickly!

I've gone by the nickname 'Pongo' for many years now in both my professional and personal life. It's part of my online identity on social networks like facebook, instagram, etc. In addition to this, my coworkers (in a professional office setting) call me Pongo to avoid confusing me in conversation with our coworker Erin. I like this name because it is both fun and identifiable. 

My question is this: would it be memorable to introduce myself to professionals in the Real Estate world as Pongo, or unprofessional and confusing? I realize that Aaron is not the most common name ever, so perhaps it's a fruitless exercise...but I'm viewing this as an opportunity to create a "Pongo the Real Estate Investor" identity. It's a hat that I can put on and take off, as well as a means to stick out in people's minds.

BP - what do you think?

Thanks to everyone who provided input for me. I appreciate you all taking the time to share your opinions. I think I'll stick to introducing myself with my legal name but utilize my nickname later in my professional relationships as a way to build rapport. 

Thanks again!
