Summary
🤩
RockstarDorian Zheng is a founder and seasoned database engineer with 11 years of experience building high-performance backend systems and distributed storage. Based in Singapore, he led StarRocks as Team Lead and contributed substantial backend and parquet/Hive integrations to a Linux Foundation project focused on sub-second analytics. A prolific open-source contributor, Dorian has made targeted improvements to TiKV and RocksDB—adding metrics, fixing data races, and enhancing storage engines like Titan—to boost reliability and observability in production databases. He blends hands-on systems engineering with product leadership, now founding BoxLite and a stealth AI agent startup to bring runtime AI capabilities to market. Notably, his work often targets low-level I/O, compaction, and metric instrumentation—areas that directly raise data platform robustness under heavy load.
