I build Snowflake and Databricks pipelines for banking and enterprise reporting.
IndiaWhat I'm looking for
At Cognizant, I build Snowflake and Databricks data platforms for enterprise reporting and core banking.
I've delivered ETL/ELT pipelines that ingest incremental Amazon S3 files into Delta Lake and Snowflake, using PySpark and Spark SQL across bronze, silver, and gold lakehouse layers.
For the Toscanini TSA Data Model Implementation, I improved pipeline performance through repartitioning, shuffle tuning, and Databricks cluster sizing. I also reduced Snowflake compute costs by rewriting reporting queries, applying clustering keys, and right-sizing virtual warehouses.
On TEMENOS Core Banking, I migrated Oracle data into Snowflake, designed SCD Type 2 dimensions, and implemented CDC-driven loading for audit, regulatory, and management reporting. I bring hands-on ownership across data quality, reconciliation, UAT, production support, and Agile delivery.
