I'm developing in Python, Scala/Java and some Rust. Mostly my activities are related to the Apache Spark / PySpark ecosystem and Data Engineering tools.

I'm a maintainer at the following projects:

  • GraphFrames -- scalabale graph algorithms on top of Apache Spark DataFrames.
  • Apache GraphAr (incubating) -- universal "open-table" format for storing Property Graphs.
  • graphframes-rs -- vertex-centric graph algorithms on top of Apache Datafusion.
  • spark-fast-tests -- Apache Spark testing helpers and assertions (Scala).
  • chispa -- Apache Spark testing helpers and assertions (Python).
