Puneet Oberai is a senior software engineer with 13+ years building high-performance, fault-tolerant distributed systems across infrastructure leaders including AWS, Netflix, Apple, Oracle Cloud, Stripe and now OpenAI. He has deep operational experience running multi‑TB database clusters and designing scalable services used in production at massive scale, from SQS and identity systems at Amazon to real‑time stream aggregation at Netflix. At Netflix he authored Turbine, an open‑source, low‑latency SSE aggregator used to monitor thousands of instances across regions, and contributed core enhancements to the Cassandra Java client for atomic batch updates. His work blends systems design, performance optimization, and hands‑on backend engineering—often improving aggregation logic and connection resilience in high-throughput pipelines. Based in Los Gatos, he pairs a USC master’s in CS with a track record of shipping reliable, data‑intensive infrastructure that keeps cloud services observable and resilient. An understated strength is his focus on maintainability and operational readiness, evident from extensive code documentation and production-hardened tooling.
