Károly spent the 1990s as a columnist and editor of Hungary's then-largest computing monthly, Chip Magazine. After that, he turned to web programming. His life and Drupal got hopelessly entangled in 2004. Since then he has risen to be one of the most prolific core contributors and had a brief stint as the first leader of the security team. These days he is the senior software architect for Examiner.com, one of the biggest Drupal-based websites. He is very intrigued about cognitive sciences and considers Orson Scott Card's Ender's Game as the Book.
