About Me

About Chris Muller

My experience with creating websites on the Internet ranges from simple static websites with a few pages to complex websites with a variety of applications. Although web development usually covers the main non-design aspects of creating websites, in most cases I have also done the graphic design for the websites I have created. I have acquired some graphic design skills over the years, especially in the print shop I owned for 25 years.

More than 20 years experience in web development
