I worked at ConsenSys, a large Ethereum blockchain startup studio, for 2 years on various Enterprise projects and developed an open source Ethereum PHP library and Drupal Ethereum Module that was presented at DrupalCon and DrupalEurope.

In collaboration with Heggelbach Farming Collective I helped with their website refresh of a 10 year old website using WordPress’s new Gutenberg Editor and a customized theme.

Working with a great team at Data in Transit we relaunched the website of the University Bonn Rhein Sieg (h-brs.de). At Drupalcamp Berlin 2014 my colleague Antje Gellweiler and me shared our experience of creating a responsive UI for about 40,000 Drupal pages.

My oldest project - the site for my parents' motor-home company - didn't survive the financial crisis and is offline now. We were one of the first in the branch in Germany using the internet. Since 1998 we were creating links and google rank for the website with an integrated sales-database.

A database for media cables was one of my early projects during study times. It is realised in php/html and provides restricted access for different user roles. Today I would realise the same project with a Drupal installation, which is more flexible and much easier to extend.
