Hey, I’m Julius Fedorovicius
I founded Analytics Mania in late 2016. Since then, the blog has grown to over 50000 monthly visitors. Here I share my knowledge, experiments, and learnings related to web analytics, mainly Google Tag Manager and Google Analytics.
I also run the Google Tag Manager community on Facebook where awesome people from around the world help each other.
Last but not least, I actively help others to learn Google Tag Manager by running workshops and creating GTM online courses.
