@kennedykings
QA Engineer testing web, mobile, and revenue-management systems; authored 150+ test cases for Nigeria Revenue Service.
What I'm looking for
At Nigeria Revenue Service (NRS), I tested tax-filing workflows, correspondence, and employee-directory modules. I authored and executed 150+ manual test cases and mapped coverage to requirements with a traceability matrix.
I performed functional, integration, user-acceptance, and REST API testing, using Postman to check response codes, JSON responses, and authentication-token behaviour. I tracked defects in Azure DevOps and Jira and contributed to defect-triage discussions.
At Cazoo, I tested an automotive e-commerce marketplace across product listings, checkout, and email delivery. I also created Postman checks for API requests, authentication, pagination, response times, and UI-to-API data consistency.
I'm currently carrying out freelance web and mobile testing assignments through TesterWork, documenting defects and retesting fixes. I’m also building a Playwright automation project in TypeScript for user journeys including login, registration, directory search, and multi-step forms.
