Summary
👤
Senior🎓
Top SchoolBharath Krishna is a senior software engineer and Apache committer with a decade of experience building distributed metadata and storage services for data platforms. Currently leading storage and metadata efforts at Roku and an Apache Gravitino committer, he has designed cross-cloud metadata sync, metastore-driven access control, and table retention systems that improve scale and governance. His background includes architecting a multi-tenant config push pipeline at Google Cloud and contributing to core projects like Apache Hive and Impala, where he fixed critical metastore event handling and HiveServer2/WebUI issues. Comfortable across backend systems, streaming pipelines, and database internals, he consistently bridges product needs and low-level robustness. Notably, his open-source work on Hive and Impala demonstrates a knack for preventing subtle metadata regressions by validating event timing and configurations. Based in San Jose, he combines production-grade engineering with academic rigor from a CS master's at Stony Brook.
