I am a principal engineer at IBM working primarily on machine learning on Apache Spark. I am an Apache Spark committer and PMC member and author of Machine Learning with Spark.
Previously, I cofounded Graphflow, a machine learning startup focused on recommendations. I've also worked at Goldman Sachs, Cognitive Match, and Mxit.
I am passionate about combining commercial focus with machine learning and cutting-edge technology to build intelligent systems that learn from data to add business value.
