Senior Data Analyst at Thoughtworks who standardized governed KPI logic and cut cloud compute spend by 42%.

At Thoughtworks, I analyzed stakeholder questions across 100+ distribution centers and improved executive dashboard freshness by 65%. I standardized KPI logic in a Databricks and Synapse semantic layer, enabling four domain teams to self-serve governed data.

I also documented metric definitions, source lineage, and reusable SQL patterns in Unity Catalog and dbt assets. I introduced natural-language exploration of Snowflake data with Bedrock and LangChain, and embedded data contracts, schema validation, and testing to catch breaking changes before release.

At IQVIA, I queried and modeled commercial, rebate, and clinical data for Tableau and Power BI reporting. I integrated HL7/FHIR streams into a patient analytics layer, accelerating clinical-trial reporting by 40%, and helped reduce month-end close processing from 10 hours to 4.5 hours.

Earlier, at Confluent, I supported a healthcare warehouse migration and created transformations for claims and EHR data. At Citrix, I analyzed product telemetry and automated reporting workflows, improving data availability and reducing daily processing time.
