About Me

I am a freelance software developer, work with JavaScript and Ruby on Rails. Since 2012 I live in Berlin. I enjoy most to work in a small company with a pragmatic approach.

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 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.
