What I'm looking for

I’m looking for Kolkata or remote opportunities where I can lead Snowflake data platform BAU, optimize performance, deliver secure analytics, and support Oracle/SQL Server to Snowflake migrations for enterprise BI and ETL/ELT needs.

I’m a Senior Snowflake Developer with 12+ years of IT experience across Data Warehousing, BI, and cloud analytics. I build and operate Snowflake platforms with deep expertise in Streams, Tasks, performance tuning, and security, alongside Azure Data Platform, DBT, and Databricks.

In my recent role with Tata Steel Europe, I led BAU operations for Snowflake-based BI and Datamart platforms, implemented incremental processing using Streams & Tasks, and improved report execution times through query tuning. I’ve also handled Oracle/SQL Server to Snowflake migration (reconciliation and validation), managed 120+ scheduled ETL jobs with Control-M, and supported production incidents and enhancements via ServiceNow while mentoring junior developers.
