Hey there! I'm the data scientist behind these Google Looker Studio classes. Why building classes? The need of leaving my mark? Maybe. I also could have invaded Russia like Napoleon I guess.
I've been using this tool on a daily basis for the past years and gathered a lots of knowledge that is not documented anywhere. And the time has come to leave this legacy to you (or to your team).
Spoiler: you'll get so much value out of these courses that you might want to send me a thank you card. And flowers. I do like flowers.
If anything, please contact me, I'll do my best to give you the best answer. About Looker Studio or life in general. Don't smoke, it's bad for you.
