My full name is Conrad Pascal Buranicz. I like telling people that my middle name comes from the programming language, but its actually from the Saint. My parents are both immagrants from Poland, and thats where my last name comes from.
On the other hand, my Great Grandfather was named Conrad. In preschool, my brother Patrick and I had a nextdoor neighbor named Robbie. Our neighbor called us Pat and Con. The three of us were Pat, Con, and Rob. In middle school I started going by Con. However, to avoid all the puns (Conman, Con Artist etc) I added an extra N to my name circa seventh grade. My brother started writing his name as Patt. So we were now Patt and Conn through high school and college!
For my professional career, most people call me Conrad. Thats what it says on my nametag, and I never try too hard to make Conn stick. So, professionally I guess I go by Conrad, but my friends call me Conn!
