Radu Berinde is a Member of Technical Staff at Cockroach Labs with a decade of experience building high-performance, distributed backend systems and databases. He holds both a BS and MS in Computer Science from MIT and previously served as a Sr. Staff Engineer at VMware, bringing deep systems and production engineering expertise. Radu is an active open-source contributor to flagship projects like CockroachDB, Pebble, and the Go runtime, where his work has improved MVCC engine performance, memory management, sstable/compaction internals, and optimized CRC32 with low-level AMD64/SSE4.2 enhancements. He combines practical engineering—shipping downloads APIs, tests, and bug fixes—with low-level algorithmic tuning, a mix that surfaces both reliability and measurable performance gains. Based in San Diego, he favors solving hard systems problems that sit at the intersection of database theory, storage engines, and CPU-level optimization.
