Senior Tracking & Analytics Engineer
I build and fix tracking for GA4, Google Tag Manager, server-side tagging, and advertising platforms. Because I have been developing software for more than 20 years, I also look for errors where they often originate: in the shop code, in the backend, and on the server.
For companies and agencies, directly or as white-label support.

About me
I studied technical mathematics at the Technical University of Munich and have worked as a self-employed software developer since 2002. For many years I developed and operated platforms, from press portals to payment systems. Today my focus is on tracking and analytics. The experience from backend, infrastructure, and operations feeds directly into this work.
I am also co-founder, managing director, and technical lead of ProxyRiders GmbH, which hosts Google Tag Manager tagging servers in Germany.
A practical starting point
Start with a focused diagnosis
Missing conversions, duplicate purchases, or numbers that do not match between GA4, Google Ads, and the shop: a scoped analysis identifies the cause and shows what needs to be done.
