Slice Analyzer

The goal was to automatically identify what treatments should be given to what audience, e.g applying a read more button to users in the US that come from Facebook. The application crunches very big data in a short time and produces a matrix per treatment in which the rows are different dimensions (e.g geo, referrer, combinations) and the columns are key performance indicators (KPI) (e.g views, clicks). The application was built using Spark, HDFS, Vertica, and Spring.
