Summary

Senior🎓
Top SchoolZhanwei Wang is a cofounder and distributed-systems engineer with 11 years of experience building high-performance SQL-on-Hadoop systems and databases. As the first developer of HAWQ at Pivotal and now an Apache HAWQ committer and PMC member, he led design and implementation of HDFS access, metadata dispatch, and a novel transaction control that enabled stateless, highly scalable segments. At HashData he continues to focus on cutting-edge Big Data solutions including Spark integrations and security-aware HDFS querying. His hands-on contributions to the apache/hawq project include fixing build and test issues, improving append-only data consistency, and hardening initialization and dependency handling—work that kept a major open-source analytic database production-ready. Based in Chaoyang District, Beijing, he blends deep academic training (M.Eng. in Software & Theory) with entrepreneurial product-building experience. Notably, he designed concurrency- and partition-resilient mechanisms that address data-race and scalability challenges uncommon in many commercial Hadoop SQL engines.
