At Deloitte USI, I design Azure Data Factory pipelines to ingest and integrate data from enterprise sources. I also develop PySpark notebooks in Azure Databricks for distributed processing and ETL workloads.
I use Azure Data Lake Storage Gen2 for structured and semi-structured data, and build transformation workflows with Spark, PySpark, and SQL. My work includes data migration support, source-to-target mapping, validation, reconciliation, and data quality checks.
Before Deloitte USI, I developed ACH banking applications at Fiserv India Pvt Ltd and telecom billing applications at Amdocs. I also worked on batch processing, SQL optimization, production support, and legacy application enhancements.
