Summary
🤩
Rockstar🎓
Top SchoolBikramjeet Vig is a seasoned software engineer with 10 years of experience designing and optimizing high-performance distributed query engines and execution runtimes. Based in the San Francisco Bay Area, he currently contributes to Velox at Meta and serves on the Apache Impala PMC, bringing deep expertise in C++ native execution, memory management, and query lifecycle optimization. At Cloudera he advanced Impala’s scheduler, admission control, and Kubernetes-based virtual warehouse features, and his open-source contributions include native-execution improvements and new Presto/Velox functions that enhance performance and correctness (e.g., overflow checks and lazy spill creation). Bikramjeet pairs strong academic credentials—a perfect 4.0 MS in Computer Science from USC and an IIT Roorkee B.Tech—with hands-on systems debugging and instrumentation, including adding memory-allocation metrics and improving NaN handling. He’s equally comfortable implementing low-level execution details and shaping project governance as an active committer and PMC member.
