Xiaoman Dong is a founding engineer and seasoned backend engineer with 10+ years building high-throughput, real-time data systems across startups and large tech firms in the Bay Area. He has deep expertise in OLAP, streaming (Kafka), and cloud-native operations, demonstrated by production work on Apache Pinot (real-time distributed OLAP) and contributions that improved service discovery, TLS support, and stability of broker/server startup paths. His career spans core roles at Parasail, Nuro, StarTree, Stripe, Uber, and HP Vertica, where he led performance-sensitive database and streaming projects and owned complex execution and join logic. Equally comfortable architecting and shipping, he bridges low-level systems optimization with cloud DevOps — recently speaking about fully managed Kubernetes clusters. A pragmatic problem-solver with roots in mechanical engineering from Tsinghua, he brings a systems-first mindset to scaling LLM infrastructure and real-time analytics.
