GitHub Sponsors Profile
I am a software architect, open source leader and entrepreneur who loves collaborating with others in Open Source projects. I started the Parquet project in collaboration with the Impala team at Cloudera back when I was at Twitter. I chaired the project for many years at the Apache foundation and Parquet is now the de-facto standard for data lakes. I later contributed to the creation of the Arrow project as a founding engineer at Dremio. Before that I received my initiation contributing to OpenSource in the Apache Pig project at Yahoo where I evolved from contributor to committer to PMC member and eventually chaired the project in 2013. More recently I started the OpenLineage project while being the CTO and co-founder of Datakin which was later acquired by Astronomer. OpenLineage came out of Marquez, the project we co-created at Wework on the data platform team.
I currently lead the OpenLineage project, facilitating discussions, ensuring all voices are heard and empowered and growing its ecosystem.
