Google Tag Manager freelancer

Quick introduction

My name is Lucas Rollin, and I’m the founder of Data Marketing School.

I’m from Rennes in France (1h30 by train west of Paris).

I studied computer engineering, but as soon as I finished my work-study placement as a full-stack developer for a large insurance company, I turned down my permanent contract to go freelance.

After some experience in Media Buying, I finally found my genius zone in tracking.

In 2023, after helping a few clients set up their Google Ads conversions and Google Analytics events, I launched the Data Marketing School blog.

Tracking being a complex and obscure subject for many people, the idea of this blog is to help the community (including me) to better understand this universe via free tutorials.
