At Coopersystem, I executed manual and automated functional and non-functional tests for mobile applications and APIs, including integration, regression, performance, and security testing. I used Selenium for automation and SQL to verify data integrity, and managed tests and defects with Jira and Manthis.
On the Hospital Militar da Área de Brasília consultation system project, I participated from requirements understanding through test planning and execution, and helped organize acceptance testing with medical and administrative professionals. My work contributed to implementation with few reported bugs and positive feedback on usability and efficiency.
