Summary
🤩
Rockstar🎓
Top SchoolBiswapesh Chattopadhyay is a Distinguished Engineer based in Sunnyvale with over two decades of experience architecting exabyte-scale data, analytics, and distributed systems for companies like Google and Meta. He has repeatedly built foundational engines and storage — from Tenzing and Procella to lakehouse and columnar formats — that power millions of QPS and trillions of rows, while delivering order-of-magnitude performance and cost improvements. At Google he drives unified analytics, Zetta-scale lakehouse storage, and resource efficiency; at Meta he led open-source innovations (Velox, Alpha, MetastoreX, CoreSQL) that blur the line between analytics and ML. Known for combining deep systems design with production rigor, he moves seamlessly between low-level storage/compute optimizations and large cross-organizational architecture. Collected academic pedigree from IIT Kanpur and BITS Pilani underpins a pragmatic focus on reproducible, scalable data infrastructure that often becomes the de facto platform for teams across the company.
