Joshua Gertzen is a professional software engineer with over 12 years of experience in software development and architecture. His knowledge and experience range from utilizing differing programming languages, development frameworks, and architectural patterns, to troubleshooting complex technical issues. Over the last six years, he has played a key role in building the technology infrastructure at Custom Credit Systems (http://www.customcreditsystems.com), a Dallas-based software company. A major focus during his time with that company has been on building Web architectures that utilize DHTML and/or AJAX programming techniques.
