Tim Kadlec

The closer you look at something, the more interesting it gets. That’s probably why I love it when I’m able to pore through large amounts of data related to a topic that interests me. You keep twisting and turning it enough, and you’ll eventually start to uncover fascinating trends and insights that weren’t apparent on the surface. Hence, why I’m a big fan of BigQuery.
