Rockstar🎓
Top SchoolMingda Sun is a systems-focused software engineer with over eight years in cloud storage and distributed systems, now building an in-house VectorDB at eBay. He combines deep system programming across multiple languages with practical expertise in database internals and database-as-a-service, having implemented backup/restore, PITR, and multi-zone failover features at Yugabyte and SAP. At eBay he proposed a datalake-like immutable index architecture, introduced index segmentation and sharding strategies, and designed a patent-pending LSMT-like real-time index merging mechanism. Comfortable moving between offline index generation with Spark and real-time query engines, he also mentors interns on benchmarking and recall evaluation. Based in Davis, CA, Mingda’s background spans open-source storage work (Ceph-related optimizations) to production database engineering, reflecting a blend of research-informed design and hands-on delivery.
