Senior Data Engineer with 5+ years designing and scaling data pipelines, data warehouses, and ETL workflows across AWS, Snowflake, Spark, and Airflow. At Salesforce, I work on retry-safe, idempotent ETL pipelines that cut production incidents by 40%, contribute to migrating legacy Hive tables to Apache Iceberg for zero-downtime schema evolution, and tune high-concurrency SQL across Snowflake, Hive, and Athena. Previously at ZS Associates, I built Power BI/Tableau dashboards that improved sales operations efficiency by ~30% and automated reporting workflows that cut time-to-insight by ~40%. At TCS, I reduced reporting discrepancies by ~20% through data validation and reconciliation work. I specialize in turning complex, high-volume data into reliable, decision-ready systems — partnering closely with Product, Analytics, and Data Science teams along the way.
