Other

For some years now, I specialized in OpenCms. I started programming when I was 8. Later I have worked on client-side and server-side applications, being responsible for business logic, data binding and GUI, which I euqally feel at home with.

I have been involved in various applications from conception through to successful deployment. I also have experience with writing technical and other texts.

My work ethic is heavily geared towards the goal of a high quality product with an intuitive user interface and a finished look & feel.
