I am an author, speaker, and consultant on the design of enterprise software. On this site I keep as much information as I can on-line. There are links to my books, various on-line articles, and links to areas relevant to my work. My primary areas of involvement are in object-oriented development, refactoring, patterns, agile methods, enterprise application architecture, domain modeling, and extreme programming. I work for ThoughtWorks, an outstanding application development and consulting company.
