After 28 years as a developer, architect, project manager (recovered), author, trainer, conference organizer, and homeschooling dad, Dave Klein started his developer relations journey with the Apache Kafka community at Confluent. He then migrated downstream to the lake house with Tabular, helping developers merge the worlds of streaming and batch analytics on Apache Iceberg. Now he's found the sweet spot that really brings the power of streaming and batch together with Apache Druid, at Imply.
