Message

At Infosys, I develop Snowflake solutions for the Tractor Supply project, translating business requirements into technical specifications and data solutions.

I develop and optimize Snowflake SQL transformations and support ETL/ELT pipelines using Azure Data Factory, Azure Blob Storage, and Snowflake. I also automate bulk and incremental data processing with COPY INTO and MERGE.

Previously, I supported BI analysis for Chipotle Restaurants and production data processes for Wells Fargo (WIMT). My work included SQL-based validation and reconciliation, Power BI report support, batch job monitoring with AutoSys, and incident management using ServiceNow.
