Nathaniel T. Schutta is a senior software engineer in the Twin Cities area of Minnesota with extensive experience developing Java Enterprise Edition–based Web applications. He graduated from St. John’s University (MN) with a degree in Computer Science and has a master’s of science degree in software engineering from the University of Minnesota. For the last several years, he has focused on user interface design. A long-time member of the Association for Computing Machinery’s Computer-Human Interaction Special Interest Group, Nathaniel believes that if the user can’t figure out your application, then you’ve done something wrong. Along with his user interface work, Nathaniel is the cocreator of the open-source Taconite framework, has contributed to two corporate Java frameworks, has developed training material, and has led several study groups. During the brief moments of warm weather found in his home state of Minnesota, he spends as much time on the golf course as his wife will tolerate. He’s currently exploring Ruby, Rails, and (after recently making the switch) Mac OS X. Nathaniel is the coauthor of the bestselling book, Foundations of Ajax.
