Nayanika Upadhyay is a software engineer with 5 years of experience building high-performance distributed systems, in-memory caching, and cloud-ready data platforms across Netflix, Yahoo, and NetApp. She helped scale Netflix’s Hollow-based publish/subscribe and key-value services for versioned datasets and contributed backend fixes and performance improvements to the widely used Netflix/hollow project. Her work at Yahoo included latency-optimizing mailbox caches, HBase schema migrations for millions of users, and rate-limiting and categorization services that reduced operational load. Comfortable in both systems design and hands-on engineering, she has a strong background in storage, SANs, and network-aware simulations from earlier NetApp research. Based in the San Francisco Bay Area with an MS in Computer Science from UC Irvine, she’s focused on Distributed Systems, Big Data, and Cloud Computing and brings a pragmatic, performance-first approach to production systems.
