## About

```text
At Tata Consultancy Services, I contributed to the Humana healthcare claims data pipeline, developing pipelines to ingest and transform member, provider, enrolment, and claims data.

I supported the migration of healthcare claims data from on-premises SQL Server to Azure Data Lake Storage Gen2 using Azure Data Factory and PySpark. I also performed data validation and source-to-target reconciliation.

I used incremental loads and Delta Lake upserts, and developed parameterized Azure Data Factory pipelines. I handled data quality issues and schema changes during ingestion and transformation.

On SBI’s YONO 2.0 project, I provided backend support, using SQL to validate data and Linux logs to help investigate issues. I hold a B.E. in Computer Science and Engineering from K.S.R. College of Engineering.
