Rockstar🎓
Top SchoolRussell Spitzer is a Principal Engineer based in New Orleans with 12 years of experience focused on distributed systems, large-scale data processing, and query optimization. He has deep open-source credentials as an Apache contributor and Iceberg PMC member, with notable backend contributions to high-profile projects like Apache Spark, Cassandra-Spark connector, and Apache Iceberg that improved SQL predicate pushdown, PySpark session extension handling, and snapshot/data-file rewrite semantics. His career spans production engineering and management at Apple and DataStax, and he currently works at Snowflake, bridging core data-engine internals with cloud-scale product needs. Trained as a PhD bioinformatician and dual-major in math and CS, he brings rigorous research instincts to practical system design and testing. Colleagues know him as the engineer who thinks obsessively about distributed systems (and also likes dogs), combining curiosity-driven problem solving with a steady record of shipping robust infrastructure.
