Josephus Callaars is a software developer whose passion began like so many other developers at the appropriate age of twelve. Being intrigued by mathematics and software languages such as Assembler and Java, he quickly found out that his career was to be found in the abstract side. Since 2003 he has been developing software applications commercially, and always tried to stay up-to-date with the latest technologies.
Josephus has been passionate about developing ever since, and always thought it could be done better every time. He is a Zend Certified Engineer and is regularly to be found in the open source community, where he is always on the lookout for new things to learn.
