Stefan Richter is a Director of Engineering and former Principal Engineer with a decade of experience building and optimizing distributed query and streaming systems, now leading Streaming SQL and the core Flink runtime at Confluent. He holds a Ph.D. in database systems from Saarland University and played a key role in creating Apache Flink, contributing notably to the Scala CEP API and cross-language interoperability. Previously he drove query processing and search optimization at Snowflake and built state management and runtime components for Flink at Data Artisans.
