ETL and data warehouse test engineer at Dataction Analytics, validating Jet2holidays data and Tableau reporting.

At Dataction Analytics, I validate ETL, data warehouse, and Tableau reporting for Jet2 Travel Technologies / Jet2holidays, using SQL for source-to-target checks and data reconciliation. I also test REST APIs with Postman and validate request and response data against backend records.

For Warner, I supported Tableau-to-Power BI dashboard migration, reconciling reports and checking KPIs, filters, and Row-Level Security. Earlier at Tek Arch technology, I developed and executed automated data validation tests in Tricentis Tosca for the Cummins data platform modernization project.
