ProxyRiders
In 2024, together with Jochen Plinta, I founded ProxyRiders GmbH, based in Grünwald near Munich. The company hosts Google Tag Manager tagging servers in Germany for agencies, online shops, freelancers, and others. As managing director and technical lead, I am responsible for the infrastructure, operation, and development of the platform.
On proxyriders.com, I write articles about hosting, operating, and estimating server-side tagging.

How the earlier work strengthens the current offer
Tracking implementations regularly fail outside the tag manager itself: incomplete application events, payment redirects, identity boundaries, APIs, malformed values, browser security rules, deployment differences, or production infrastructure. The earlier software and operations experience makes those parts of a measurement system accessible rather than external dependencies. Through ProxyRiders, I also know the long-term operation of tagging servers: custom domains, scaling, monitoring, and costs.
Working context
- Freelance and remote work
- Collaboration in German and English
