David Mercer was born in August 1976 in Harare, Zimbabwe. Having always had a strong interest in science, David came into regular contact with computers at university where he graduated “cum laude” with majors in applied math and math. His technical books are now sold worldwide and have been translated into French, German, Polish, Greek, Spanish and many more. His book on Drupal 6 was reviewed on Slashdot and went on to become a best seller. Mercer’s books are recommended reading at higher learning institutes like MIT, and he has a write-up on Wikipedia. David divides his time between consulting for companies and organizations in a wide variety of industries, helping them to develop and implement cutting edge systems. He also contributes to interesting web-based projects like design-a-webpage (http://www.design-a-webpage.com) that allows people to create beautiful, effective landing pages in minutes – absolutely no code or Web experience required. He also maintains a blog, training and support site for his readers at http://www:siteprebuilder.com. Site prebuilder provides quizzes and exercises that accompany his books, and serves as his primary online presence and contact point. When he isn’t working (which isn’t that often) he enjoys playing guitar (generally on stage and unrehearsed) and getting involved in outdoor activities ranging from touch rugby and golf to water skiing and snowboarding.
