At Cognizant Technology Solutions, I spearheaded the migration of Novartis Pharma AG enterprise reporting from Qlik Sense to Microsoft Power BI. I also engineered reporting ETL workflows with Databricks, PySpark, Spark SQL, and T-SQL.
For Novartis, I optimized LEAP material transformation processes to improve dashboard stability and refresh reliability. I coordinated release management and deployments while maintaining GxP compliance.
Earlier at Cognizant Technology Solutions, I architected metadata-driven Snowflake validation workflows for Merck KGaA and automated cloud orchestration with AWS Lambda, Step Functions, and Terraform. I introduced TestCase-GPT, which uses multiple LLMs to automate Excel-based test generation and improved team productivity by approximately 70%.
I also built a sales analytics platform using PySpark, Databricks, Amazon S3, Amazon Redshift, and Amazon QuickSight. My work spans cloud data engineering, analytics, and automation for pharmaceutical clients.
