Über mich


I have been working in the field of web analytics since 2015.  I help organizations to collect, evaluate and apply information about the digital interaction with their users. 

Tools like Google Analytics, Matomo or eTracker help to capture user behavior in apps or websites. I use the respective tag managers from Google or Matomo for more complex data collection and script management. 

Other methods to collect data about the user experience are interviews, surveys, crawlers or benchmarks. 

From reports or dashboards to analytics bots, I use the interface that makes the data most accessible to users. 


Und wer bist du?
