He is a self-described LaVeyan Satanist, and bears an upside-down cross tattoo on his right arm. His persona is an apathetic badass programmer that has libertarian tendencies. To say he is odd is an understatement.

Memorable Quotes

"What do I do? System Architecture. Networking and Security. No one in this house can touch me on that. But does anyone appreciate that? While you were busy minoring in gender studies and singing acapella at Sarah Lawrence, I was getting root access to NSA servers. I was a click away from starting a second Iranian revolution. I prevent cross site scripting, I monitor for DDoS attacks, emergency database rollbacks, and faulty transaction handlings. The internet, heard of it? Transfers half a petabyte of data a minute, do you have any idea how that happens? All of those YouPorn ones and zeros streaming directly to your shitty little smart phone day after day. Every dipshit who shits his pants if he can't get the new dubstep Skrillex remix in under 12 seconds. It's not magic, it's talent and sweat. People like me ensuring your packets get delivered unsniffed. So what do I do? I make sure that one bad config on one key component doesn't bankrupt the entire fucking company. That's what the fuck I do."
