Validate Business Intelligence (BI) reporting solutions, analytical dashboards, data integration pipelines, and complex SQL queries for data integrity.

Ensure test automation scripts and code bases are maintained under source control with full documentation and disaster recovery processes in place.

Partner with developers, software architects, and product owners to transform business requirements into comprehensive test strategies, test plans, and test cases.
