Message

At R1 RCM, I support healthcare RCM data processing across SQL Server, ADLS, and Databricks, including 1 TB+ of daily data. I implemented incremental ingestion of 200+ daily CSV files into Bronze Delta tables and strengthened data validation across claims, payments, and operational metrics.

I also contributed to optimizing SQL transformations and PySpark based data processing workflows, reducing pipeline execution time by 45%.

Earlier at Accenture Solution Pvt. Ltd, I crafted and deployed 12+ Power BI dashboards using DAX to automate manual reporting. In personal projects, I’ve explored event-driven data pipelines and customer purchase behaviour analysis.
