Summary
🤩
Rockstar🎓
Top SchoolAnkit Singhal is a Director of Engineering based in the San Francisco Bay Area with over a decade of experience designing and operating large-scale data platforms and distributed systems. He blends deep Java and NoSQL expertise with hands-on work across Hadoop ecosystem tools (Hive, Pig, Sqoop), HBase, and cloud/colocated deployments, and has driven reliability and performance improvements in critical open-source projects like Apache Phoenix and HBase. As an Apache PMC vice-chair and committer across Phoenix, HBase and Ratis, he routinely solves subtle database correctness and memory-management issues—work that underpins enterprise-grade OLTP/analytics scenarios. Prior roles at Cloudera and PubMatic show a pattern of moving from individual contributor to engineering leader while still contributing code and architecture decisions. He holds a B.Tech in Computer Science and is known for combining pragmatic engineering with a willingness to dig into low-level bugs that others avoid.
