At IBM India Pvt Ltd, I led the Teradata-to-Snowflake migration across data hubs including Commercial Analytics, Supply Chain, Braze, and IPOR. I built and optimized Databricks ETL/ELT pipelines that load data from AWS S3 and REST APIs into Snowflake, and tuned Snowflake SQL and Spark SQL queries.
I also enhanced Finance hub pipelines and maintained DIRECTV volume and revenue reports. Earlier at IBM, I developed Informatica mappings for the Blue Cross Blue Shield Data Access Layer project; at Capgemini Technology Services, I worked on Hartford Steam Boiler data integration and production support.
