Jose Argudo is a web developer from Valencia, Spain. After finishing his studies, he started working for a web design company. After six years of working for that company, and others, he decided to start working as a freelancer.

Now, he thinks it's the best decision that he has ever taken, a decision that lets him work with the tools that he likes, such as Joomla!, CodeIgniter, CakePHP, jQuery, and other known open source technologies.

In the last few months, he has reviewed books for Packt Publications such as Magento 1.3 Theme Design, Magento: Beginner's Guide, Joomla! 1.5 SEO, Joomla! with Flash, and Symfony 1.3 Web Application Development, along with Magento 1.3: PHP Developer's Guide.

If that weren't enough, he authored CodeIgniter 1.7 for Packt Publications, a book that he put a lot of effort into.

Erik Hansen is an entrepreneurial techie with a bent for business. He's the co-founder and CTO of Classy Llama Studios, an e-commerce-centric company that he helped start in 2007. He leads a team of developers in providing creative solutions for Classy Llama's clients.

Hansen's interest in technology is hard-wired in his brain. He started out building basic circuit boards in his basement as a child, and after being involved in a number of startups right out of high school, he focused his efforts to become an expert in Magento e-commerce development.

When he's not staying up until the wee hours of the morning programming (on his MacBook Pro, of course), Hansen enjoys spending time with family and friends, reading, playing sports, and listening to music.
