I have been working with PHP since 1996. I started working with the TYPO3 CMS enterprise content management framework in 2000. I Iove to create and share useful tools for working with TYPO3 CMS. Throughout the years I've picked up many other languages and frameworks. I'm always on the lookout for ways to expand and improve my toolchest. I love exploring and learning new programming languages, frameworks and tools. I build whatever tool gets the job done:

And lots of other tools. What would you like me to build for you?
