Hi, my name is Karin Huber. Since 1998 I have been working as a developer and IT consultant focusing on building database oriented web applications. In 2007 my friend Rainer and I decided that we want to build a business based on COTS (component off-the-shelf) software. As a result we founded "software architects".

These days we are offering our first version of the time tracking software called 'time cockpit'. You can find more information at www.timecockpit.com.
