Hello World!

I’m Katrin Sellerbeck and have been developing websites since 2003.
I like collaborating with others and finding smart, suitable solutions for complex tasks.
Travelling to the world’s ends is as enjoyable to me as exploring new ideas and technologies.
Other things I love are Science-Fiction stories, Yoga and minimal music.
Currently I am living in Berlin Kreuzberg.

If you need expertise for your website or you are looking for an experienced backend developer, feel free to contact me.
