Senior Azure Data Engineer who cut pipeline runtimes with incremental loading and optimized Delta Lake layers.

At Infosys, I designed and built Azure Data Factory and Azure Databricks pipelines for an enterprise e-commerce data lake. I processed daily data into ADLS Gen2 and supported analytics for business units.

I engineered Bronze, Silver, and Gold Delta Lake layers using Medallion Architecture. Partitioning, caching, and Spark job optimization reduced downstream query runtime by about 35%, while incremental loading cut pipeline runtime by approximately 40%.

At TCS, I built metadata-driven Azure Data Factory pipelines for a retail sales warehouse, consolidating data from source systems. Incremental loading cut daily load times by about 25%, and Mapping Data Flows supported cleansing, transformation, and validation.

Earlier, at Flex, I developed Azure Data Factory pipelines and reusable parameterized templates for retail sales data. At Genius Consultants, I built integration services with SoftwareAG webMethods and wrote custom SQL for data extraction and validation.
