Senior Snowflake Developer at HCL Technologies who automated Nestle data ingestion and migrated SQL Server data to Snowflake.

At HCL Technologies, I work on NES WH, a Snowflake data repository for Nestle. I designed and automated data ingestion with dbt and implemented a migration from SQL Server to Snowflake.

On Ericsson’s data lake project, I worked on migrating data from multiple technologies to Snowflake, including building Snowpipe and rewriting Informatica ETL. Earlier, I worked on data engineering and Hadoop administration projects, including cluster operations and ETL development.
