Hi, My name is David Vallejo and as you already guessed I’m the person behind this Analytics and Tagging related blog.

Actually I work as a freelancer in Spain  mainly doing web/app analytics implementations and audit for clients around the world. 

My main expertise is about doing analytics implementations on almost any tools but mainly focused on using Google Analytics along with Google Tag Manager / Tealium

I would say my main strength comes from having a seasoned background on Infrastructures ( I worked offering servers outsourcing for 6 years in the past ) and some self-taugh  programming skills that really do a good party along with my analytical mind. All this allows me to be able to have a full view of what a analytics tracking project needs and how to face it.
