Message

At IQVIA, I led AI-first analytics for healthcare operations and commercial teams, including LLM-driven Text-to-SQL assistants that answer business questions using governed data. I built workflows that validate results against warehouse queries and summarize KPIs for reporting.

I also built RAG-powered knowledge systems over warehouse tables and policy documents, and delivered governed analytics through Power BI, Metabase, and Databricks SQL. My work included analyzing medical, dental, and pharmacy claims for reimbursement, provider compensation, and cost-of-care analytics.

At SAS Institute, I designed conversational AI support chatbots for Shopify merchants and built analytics to measure their effectiveness. Earlier, as a Data Engineer at Deloitte, I developed ETL pipelines, data warehouse structures, and validated datasets for enterprise reporting.
