What I'm looking for

I'm looking for ETL testing and Python automation work where I can validate data pipelines, improve data quality, collaborate with engineers and stakeholders, and build scalable automation for cloud data platforms.

I've built Python ETL test automation frameworks for Global Sales-revenue-Adjustment Data at Globe Infotech, supporting Boston Scientific sales data analytics. My regression suites automate metadata, schema, and source-to-target validation across Snowflake and Databricks pipelines.

I use Python, Pandas, SQL, UDFs, and Snowflake connectors to validate transformations, reconciliation, data quality, and business reports. I've also used Gemini AI, Cursor AI, and AI-agent workflows to generate validation scripts, run checks, flag mismatches, and produce exception reports.

Previously, I supported Oracle Financial Services capital-markets work, including Oracle database migration, data mapping validation, ETL test-case design, regression, performance, and API testing. I collaborate directly with data engineers, developers, business stakeholders, and customers to validate workflows before production sign-off.
