Felix Cheung
Engineering Manager II, Uber

Felix Cheung is an engineering manager II at Uber and a PMC and committer for Apache Spark. Felix started his journey in the big data space about five years ago with the then-state-of-the-art MapReduce. Since then, he’s (re-)built Hadoop clusters from metal more times than he would like, created a Hadoop distro from two dozen or so projects, and juggled hundreds to thousands of cores in the cloud or in data centers. He built a few interesting apps with Apache Spark and ended up contributing to the project. In addition to building stuff, he frequently presents at conferences, meetups, and workshops. He was also a teaching assistant for the first set of edX MOOCs on Apache Spark.
