Hey, I'm Leo Chashnikov

Software Engineer, interested in Functional Programming and Big Data processing. Experienced in Scala, Python and Java, and working with Apache Spark.

Previously:

Small pet-projects, that I consider interesting:

spark-snippets - collection of small functions and utility classes, that I found regularly useful when working with Apache Spark
sparkling - example / test application I use as a demo in some articles on testing Spark apps, and Spark Streaming.
indexVerse - multi-threaded creation of inverted index in Scala
