My professional career started in 1996. This gives me more than 20 years of experience.
In my first Job, I joined Netlife. I became Netlife's vice president of product development and stayed until after their IPO.
In 2009, I cofounded Balao, the company who built GratisPay, and worked as its CTO. We sold Balao in 1/2010 to Fyber.
From 2010-2013 I was CTO and cofounder of Papersmart GmbH.
Today I work as a freelancer.
I am most interested in
I have written two books:
The first book is Go To JavaServer Pages. Addison Wesley published it in 2001. At the Amazon page you can find an overview and reader reviews
My second book is Spring and Hibernate. It introduces Spring and Hibernate, and how these two technologies play together in a typical project. Please see Amazon's page. Hanser published the second edition in April 2008.
From 1.4.2018 on I will be available for 4 days per week for projects in Berlin.
