Anurag Gupta

Senior Member of Technical Staff at Oracle, building backend capabilities for the Oracle Database API for MongoDB. I developed Java-based services that translate MongoDB wire-protocol commands and query semantics into Oracle SQL/JSON execution using ORDS and SODA. My work spans command dispatch, BSON/OSON codecs, cursor and session lifecycle management, aggregation-pipeline planning, SQL generation, and production testing. I have improved aggregation-query latency by up to 26% and reduced overall query execution time by 17% through query-planning and SQL-generation optimizations. I designed and delivered MongoDB $lookup support by mapping nested-pipeline semantics to SQL/JSON left-outer joins, and implemented operators including $binarySize, $bsonSize, and $addToSet across parsing, planning, and execution layers. I also owned urgent enterprise-customer feature releases end to end, coordinating design, implementation, reviews, testing, and release communication to unblock production workloads.
