About Yannis
I've spent the best part of a decade deep in GA4 and GTM, helping businesses across Europe set up tracking that actually works. My focus is implementation and making sure the data actually gets used, from GA4 setups, marketing pixels, server-side tracking and BigQuery to measurement strategies that help teams make better decisions.
