I'm a senior software engineer at Red Hat, writing open source software for fun. They also pay me for that.
Spark Exception Handling
I contribute (mainly) to the following projects: JBoss Fuse, Apache Karaf, Fabric8, Apache Camel, Hibernate OGM.

I'm passionate about Apache Spark and wrote some libraries based on it.

Spark-HBase-Connector: to let Spark interact with Apache HBase with ease.
Spash: a Bash-like console to interact with a Big Data cluster.

I worked at Engineering Ingegneria Informatica S.p.A. (Italy) before joining Red Hat. Last experience at Engineering was about leading a team of 20 developers to create a new MDM (Meter-Data-Management) system based on Apache Spark, Apache HBase, Kafka and Hadoop.
