I perused the comments and didn't see anyone mention this. The term "engineer" is regulated by every state in the US. I doubt they had Tinder in mind, but calling yourself an "engineer" without having a Professional Engineer license is illegal, at least when it comes to offering professional engineering services. It's a protected title so that schools and bridges don't get built by scammers--at least that was the intention. I can legally call myself an Engineer!
Just go get your license, and you should be golden lol.
