Joe’s primary background is in software development - primarily in the form of Web and Mobile applications.  For the past number of years, he has used technical writing as a means of learning about technologies, frameworks and languages that he wouldn't have regular exposure to in my day job. He has written over twenty articles and tutorials for IBM developerWorks, on topics such as DB2, Node.js, AngularJS, MongoDB, Ruby, JavaScript, HTML5, Python, PHP and more. He has also written for Smart Developer magazine and Safari Books Online. His first book, Beginning CouchDB, was published in 2009, and his second book, HTML5 in Action, was published in March 2014.
