Summary
🤩
Rockstar🎓
Top SchoolDavid Quintas is a seasoned software engineer and co-founder with 14 years of experience building mission-critical, large-scale systems across Google, Waymo, CERN and Lawrence Berkeley National Laboratory. He blends deep expertise in ML/NLP from Google Research with low-level systems work—concurrency, network protocols, gRPC and high-performance computing—having contributed directly to the core gRPC C and Node libraries. At Waymo he helped design logs infrastructure for petabyte-scale data, and his early accelerator and controls work at CERN and LBNL surfaces in robust, fault-tolerant architectures. Based in San Francisco, he pairs research-grade rigor with pragmatic engineering and a taste for low-level optimization (his GitHub work includes significant byte-buffer and native-binding refactors for grpc/grpc-node). Not obvious from titles: he equally navigates distributed storage and protocol-level internals, making him rare as both an ML practitioner and a systems hacker.
