Life In General

Karl Isenberg is a web programmer (and alum) at University of California at Irvine. He got his WoW addon start by editing a mod that converted speech to L337 and back which then progressed into the UniversalTranslator which was soon after banned and disabled by Blizzard, but not before Karl had moved onto his next project. Since January of 2005 Karl has written over 50 addons, helped debug dozens more and lead the Cosmos Development Team. Karl's WoW pseudonym started as AnduinLothar, the name of his 60 Paladin on Kil'jaeden and all the characters before him in the beta tests. More recently he goes by KarlKFI on forums and in IRC. He likes to code most of his addons for standalone use and post them on Curse and WoW Interface. In college, when he wasn't playing WoW or coding addons, Karl did Programming Research using Python, XML and JavaScript to develop an online templated PDF editor. More recently he has done self-employed web development on a couple small business sites. Currently he is waiting for Cataclysm to come out and getting married. In his free time he likes to rollerblade, play racketball and read science fiction.
