I build and operate cloud-native Azure data pipelines for healthcare-payer and retail analytics. At Tata Consultancy Services, I ingest and transform claims, member, provider, and enrollment data into ADLS Gen2 and Delta Lake.

I deliver Medallion architecture solutions, including curated Gold-layer models that support Power BI reporting for claims, membership, utilization, and business analytics.

Previously at Infosys, I helped modernize legacy Oracle data warehouse workloads into a Delta Lake lakehouse and created reusable, metadata-driven ADF pipeline templates. I embedded validation, reconciliation, audit logging, retry handling, and observability into production data pipelines.

I use Azure Data Factory, Azure Databricks, PySpark, Spark SQL, and Delta Lake to improve performance through partitioning, caching, broadcast joins, and Z-Ordering. I'm also expanding into Microsoft Fabric, Synapse, Azure OpenAI, and RAG patterns to create scalable, secure Microsoft-based solutions.
