Picture of Dirk Holtwick My name is Dirk Holtwick.

I'm an independent software developer based in Mülheim an der Ruhr, Germany.

Since 1999 I have been working with companies like Evernote, Cellular and eGenix.

I also created commercial and open source software myself like Receipts and xhtml2pdf.

My goal is to solve complex problems elegantly and therefore I have been developing with all popular technologies and operation systems. Though my favorite targets are macOS and iOS and modern web technologies.

If you like to learn more about my current project follow me on Twitter or read my blog.
