India

Message

At Tata Consultancy Services, I design and maintain Snowflake data pipelines for the USAA data migration, using Snowpipe, Streams, Tasks, and AWS S3. I build dbt workflows with embedded tests and reconcile migrated data to support reliable cutover.

At Prodapt Solutions Pvt Ltd, I maintained real-time Snowpipe ingestion and implemented Streams and Tasks for near real-time processing for CityFibre. I also integrated Kafka data into Snowflake pipelines for telecom network analytics.

Earlier at Prodapt Solutions Pvt Ltd, I developed Tableau dashboards and Tableau Prep workflows for CityFibre Customer Insights. I automated reporting with Tableau Prep and Snowflake Tasks, cutting manual reporting effort by over 50%.
