Rockstar🎓
Top SchoolKarteek S is a software engineer with 10 years of experience building high-performance distributed systems and cloud platforms, currently working on Presto at Meta to solve interactive query use cases. He has a proven track record at AWS, Ahana (IBM), and Amazon building dataplane and large-scale services, and earlier implemented modular, zero-downtime service loading at Tally to improve server responsiveness. His open-source contributions to Presto and Velox include enhancing native execution, adding SQL functions like bit_count and arrays_overlap, and hardening decimal and concurrency behaviors—work that supports widely used big-data query engines. At Philips he shipped imaging features and an AR-based next-generation user guide prototype, reflecting a blend of backend systems expertise and product-driven innovation. Based in Greater Seattle with an MS in Computer Science from USC, he brings pragmatic engineering, a focus on correctness under concurrency, and experience pushing features into production-scale distributed platforms.
