I wanted something that's close enough to my irl name so I can use it in a kinda professional setting as well. Like when I hand out my business cards and the like.
My full Pseudonym is Yulek Bagel
My irl first name is one of those common Juli- names and my last name is literally the brittish spelling of Bagel.
Since I'm from Germany, the pronunciation for Juli- names is Yuli... Like "You".
To make that clear to the English speaking realm and to make it look a bit more unique, I thus went with the Y instead of the J.
Lastly, I recently changed the first name of my pseudonym from Yulia to Yulek, since I wanted something more gender neutral.
While Julek is a diminutive masc form of Julian, it's lesser known outside of East Europe, so to your run of the mill internet user it's pretty undefinable :D.
And as a pseudo cryptid, I am very much in for that.
