8+ years of experience building backend software in various areas, including big data, web, and mobile. Spent a lot of time writing Pig, Java, and Python, although I really like Ruby.
Currently learning Spark and Scala, amongst other things.
Contributed to major open-source projects such as GraphLab, Spark, Luigi, and kafka-python.
