About the Author

Francois Garillot worked on Scala's type system in 2006, earned his PhD from the French Ecole Polytechnique in 2011, and worked at Typesafe, after a brief stint in Internet advertising. He's worked on interactive interfaces to the Scala compiler, while nourishing a strong enthusiasm for data analytics in his spare time, until Apache Spark let him fullfill this passion as his main job. He received the first Spark Certification in November 2014, and worked in London and Philadelphia, among other places. In his spare time, he can be found practicing one of a half-dozen ways of making coffee, climbing up or skiing down a not-necessarily-Alpine mountain, or sailing a not-necessarily coastal course.
