* Designed a segment-based targeting pipeline, re-architecting legacy EMR workflows into Snowflake-native incremental ELT pipelines using advanced SQL and data modeling, processing TB-scale data and reducing operational costs by 30% (saving $1M annually). * Developed an optimized data processing solution in Apache Spark using Roaring Bitmaps for incremental cardinality tracking, eliminating expensive aggregations; reduced shuffle overhead and improved efficiency, enabling faster processing, lower compute costs, and efficient compliance-driven deletions at scale. * Engineered scalable Spark (Scala/Python/SQL) pipelines on AWS EMR for identity resolution (device graph), processing TB-scale data and integrating third-party sources; improving audience targeting accuracy and driving a 20% increase in campaign reach. * Optimized large-scale SQL queries in Snowflake using clustering, partition pruning, and query tuning; reduced costs by minimizing idle time and increasing cluster utilization to 90%.
