About us

'About us' is maybe a bit too much. Basically I am working as an IT freelancer. After many Java and J2EE/JEE projects in different sectors, I am using agile methods as Certified Scrum Master in my latest projects. Since 2007 I am acting in the banking sector with Calypso as Front-to-Back-Trading system.
