Summary
🤩
Rockstar🎓
Top SchoolXiaodan Zhuang is a seasoned software leader and CEO with 17 years building large-scale distributed systems, now heading Greptime to deliver GreptimeDB, an open-source unified observability database for metrics, logs, and traces. He brings deep backend expertise from roles at Ant Group, Ant Financial and Taobao, with hands-on experience in time-series databases, messaging systems and query engines. A pragmatic engineer-founder, he contributed core performance and protocol work to projects like xmemcached, sofa-jraft, EMQX bridges, and the DataFusion-integrated query engine in GreptimeDB. Based in Sunnyvale, he combines product leadership with low-level systems chops—an engineer who still fixes unit tests, refactors core libraries, and writes CI-backed connectors. Notably, his GitHub activity spans optimizing interpreters and consensus code, reflecting a curiosity that reaches beyond databases into language runtimes and distributed consensus.
