Message

At The Coast Group Technology, I tested a fintech product across onboarding, payments, wallet, and savings flows. I created and executed test cases using manual and exploratory testing.

I tracked defects in Jira and executed tests in TestSigma, while validating API endpoints with Postman.

At The QASchool, I designed and executed manual and exploratory test cases for software applications. I also used Jira, TestSigma, and Postman to document defects, execute tests, and test APIs.

Earlier, I worked as a Software Tester at AfriPro Technology and as an IT Support Officer at NZ-PRO SUPERSPIN LTD and Elyon Graphic & Digital Planet. My support work included diagnosing hardware and software issues, application testing, and database management support.
