About David Winterfeldt

David works at SpringSource as a Senior Engineer. He is working on a Flex application for a cloud product and is also on the Spring Web Team.

David has been doing software development for over 15 years. He's been using Java since 1998 and involved in using Open Source almost as long. He's an Apache committer on Struts and Commons Validator, as well as the creator of Commons Validator (although currently no longer active on either). David has focused on Web and Enterprise development for most of his career, and started working with the Spring Framework in 2006.

David runs the website Spring by Example, which is a site for sharing Spring examples. David expects this site will become a general resource for Spring Examples and ultimately save developers time.
