About

Professional summary

I am a detail-oriented Junior QA Engineer with hands-on experience in manual testing, test case design, API validation, and end-to-end testing. I focus on ensuring product quality through structured testing, clear defect reporting, and careful analysis of user workflows.

I have executed 169 manual test cases and documented 20 defects in Jira with reproduction steps and severity information. My manual testing experience includes functional, exploratory, regression, smoke, black-box, positive and negative, and end-to-end testing.

I also have automation testing experience using Cypress, JavaScript, Cucumber, Gherkin, and the Page Object Model. I developed 93 automated end-to-end test cases covering authentication, product search, product details, cart operations, and checkout flows.

I am experienced in REST API testing with Postman, including request and response validation, HTTP status code checks, and error handling. I have also used Artillery for API performance testing and GitHub Actions for CI test execution workflows.

I bring strong analytical thinking, attention to detail, accountability, and communication skills to QA work. My background in English language teaching and transcription quality review has strengthened my ability to review content carefully, communicate clearly, and follow quality standards.
