I worked for Carnegie Mellon University Computing Services from January 1995 until June 2005. More recently I was in the employ of Sine Nomine Associates, where I was the Principal Engineer, AFS Support and Services (which means I worked on OpenAFS).
More recently I am a cofounder of AuriStor, Inc. where we build high-performance distributed filesystems, network authentication infrastucture, and other systems to improve enterprise computing tasks.
