I’m an Azure Data Engineer with around 5 years of experience designing and implementing scalable, cloud-based data engineering solutions on Microsoft Azure across healthcare and insurance domains. I build end-to-end ETL/ELT pipelines using Azure Data Factory with metadata-driven frameworks, dynamic orchestration, and robust error handling. I also work hands-on with Azure Databricks (PySpark & Spark SQL) for large-scale batch processing, transformations, and data validation.

I specialize in Medallion Architecture (Bronze, Silver, Gold) using Delta Lake, leveraging ACID transactions, schema evolution, time travel, and partitioning for structured, analytics-ready data. I implement incremental loading strategies using watermark columns, control tables, change tracking, and delta processing, and I’ve delivered enterprise data warehousing work with Azure Synapse Analytics (Dedicated SQL Pools). I focus on performance tuning and reliable operations through pipeline monitoring, SLA management, troubleshooting, and collaboration in Agile environments.
