My name is John Karczewski and I am a Software Engineer and life-long gamer with over 7 years of professional game development experience. Before getting into game development, I attended the University of Illinois at Urbana-Champaign where I earned a Bachelor’s of Science in Computer Science. After graduating, I joined Volition, Inc. where I worked on Red Faction: Armageddon and Saint’s Row: The Third. Fresh off of shipping those titles, I moved to Madison, Wisconsin and joined LGN. Over the course of 5 years with LGN I helped develop 7 games, including – Fair Play, EcoNauts, Zoombinis, and At Play in the Cosmos. When I’m not playing or making games, I enjoy cooking, binge watching TV shows, and spending time with our two cats – Gizmo and Gomez.
