About the Owner-Jeff Langr

I am a veteran software developer with a quarter century of experience. I'm recognized in the software development industry as the author of the books Agile Java (Prentice Hall, 2005), and Essential Java Style (Prentice Hall, 1999). I've also contributed a couple chapters to Uncle Bob's (Robert C. Martin's) forthcoming book, Clean Code (August 2008).

I am also the author of over 75 articles appearing in publications that include Software Development magazine (now part of Dr. Dobbs), Informit.com, Ron Jeffries' XProgramming.com site, Gamelan.com, Developer.com and C/C++ Users Journal. In addition to speaking at a number of local user group meetings, I've spoken at OOPSLA (2001), SD East (2001), Agile Developers Conference (2004), Agile2007, Cingular Wave (2001), and the World Congress for Business Analysts (November 2007).

I have a broad and deep array of experience, with heavy emphasis currently on Java/J2EE, large scale C++, object-oriented design, test-driven development (TDD), agile software development, and extreme programming (XP).

I have provided services for and worked for several Fortune 500 customers, including Marriott, MCI, and Sabre. I was an Object Mentor consultant for two years, from 2000 through 2002. I have supplied expertise for customers in a broad array of industries, including government, insurance, airlines, telecommunications, retail, software, research, religion, and finance. I've helped design and develop many successful systems, ranging in size from two-week deployed efforts to multi-million lines-of-code systems.

I have created and taught courses to hundreds of students at dozens of customers, including the Veteran's Administration, Sabre, American Airlines, Verizon, CheckFree, Enron, CarFax, Nationwide, Key Bank, Stanford Linear Accelerator Center, HP, and Visa. My university experience includes teaching a Java development course at Colorado Technical University, where I also presented an agile seminar to doctoral candidates.
