Data Egnineer, Open Source Software enthusiast, Apache Software Foundation committer.

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).
• falsa -- CLI tool for generating datasets of the H2O benchmark. Wriiten in Rust.

And other various projects.
