Projekthistorie
Worked closely with QA, product, and engineering teams to identify gaps in existing processes and design new ones to improve data quality and deliver dependable data solutions. Led data management systems, including API functional testing and API development teams, to ensure on-time test data delivery, effective stakeholder management, and strong quality assurance.
Analyzed API functionality using Confluence, Postman, and SoapUI to define test data requirements for API testing and cloud migration projects. Created and provided test datasets from databases to API functional teams, enabling accurate and efficient testing.
Worked on multiple banking applications including TSYS, NCCS, mortgage mainframe systems, and Customer Connect. Used SQL to extract and prepare test data from lower environments and created test datasets for functional, regression and performance testing.
