Message

At CustomerInsights.Al, I architected the RAG and NL-to-SQL data and metadata layer for conversational analytics across complex pharma datasets, using hybrid retrieval. I also developed prompt-management tools and reliability frameworks for compliance-sensitive AI workflows.

At ZS Associates, I built Databricks ETL pipelines and automated pharma reporting, saving a US pharma client more than 60 hours of manual work each month. I also delivered clinical trial quality and safety KPIs through Power BI.

Earlier at ZS Associates, I led a Fortune 500 client’s Azure-to-AWS cloud migration and reduced ETL runtime by 33%. I’m an AWS Certified Solutions Architect – Associate, with experience across cloud data platforms, AI products, and data architecture.
