Message

At ZS Associates, I architected an AWS S3 and Athena cloud query layer for AstraZeneca that reduced ad-hoc and recurring reporting turnaround time by 25%. I also led data processing for 5TB+ pipelines and directed a 20-person team through code reviews, UAT validation, and production deployment.

Earlier, I designed and optimized enterprise data models and dashboards for Roche, and developed Tableau Hyper data pipelines with incremental refresh and automated cleansing. At Amazon, I worked on SQL Server and Snowflake datasets and automated reporting workflows, reducing manual processing effort by 30–40%.
