Before starting his professional career, Harley worked for three years as an automotive repair technician. He spent his days changing tires, batteries, and brake pads—ultimately making cars run better and more efficiently. Today, he’s a data-mechanic. Harley is still making repairs, but he’s swapped out cars for data. As a data-mechanic, he builds efficient business intelligence tools from raw data. He repairs the impractical millions of rows of data, and turns it into functional, automated tools to deliver insights, and answer important business questions. Harley still considers himself a mechanic, he just doesn’t get his hands dirty. He is passionate about data visualization best-practices, and would love to talk more about the ineffectiveness of pie charts.
