Evan Chan is a pragmatic data architect and hands-on software engineer with 14 years of experience building high-throughput, observability-focused systems and columnar, zero-copy data stores. He combines deep expertise in Rust, Scala, Spark, Kafka and Cassandra with practical release and build engineering—evidenced by contributions as a maintainer on Spark Job Server and core work on FiloDB’s Spark integration. Evan’s work on Sui added structured tracing, Jaeger integration and memory profiling, showing a knack for making complex distributed platforms debuggable in production. Based in Canada and early-trained at Stanford, he’s equally comfortable optimizing compression primitives as he is managing dependency upgrades and release pipelines. What sets him apart is a rare blend of low-level data-layout knowledge and real-world operational experience shipping resilient telemetry and time-series systems.
