## About

I’m a Senior Azure Data Engineer with around 5 years of experience building and supporting enterprise data platforms across real estate, healthcare, supply chain and financial services\. My core experience is around Azure Data Engineering — Azure Databricks, PySpark, SQL, Azure Data Factory, ADLS Gen2, Azure Synapse Analytics, Delta Lake and Snowflake\. I’ve worked across the complete data lifecycle, from source ingestion and ETL/ELT to transformation, data quality, reconciliation and downstream analytics\. My experience includes batch and incremental processing, CDC, Medallion Architecture, data migration, schema mapping, deduplication and performance optimization\. A major part of my work has also been production support\. So when a pipeline fails or the source and target numbers don’t match, I usually trace the data across layers, identify the root cause, fix the transformation or data issue and validate the results before the data reaches downstream consumers\. I’ve worked on enterprise real\-estate data modernization, healthcare data integration, supplier\-performance analytics and financial\-data governance solutions\.
