Top SchoolDrew Gallardo is a software engineer with nine years of experience building data lake and backend systems, currently at LanceDB in Redmond and an Apache Iceberg committer. He spent four years at AWS working on data lake technologies (Athena, EMR, Spark) and contributed substantive backend fixes and API improvements to the widely used Apache Iceberg project. Drew’s contributions include OpenAPI spec fixes, shared InMemoryFileIO behavior, and catalog deprecations—work that improves API clarity and storage interoperability for large-scale analytics. A University of Washington Informatics graduate, he began practical engineering as a long-term student intern supporting institutional software before moving into cloud-scale data platforms. He combines hands-on backend engineering with open-source stewardship, quietly improving developer ergonomics in critical data infrastructure. Based in Redmond, he brings a pragmatic focus on robust APIs and storage correctness that pays off in production data pipelines.
