About

As a result-oriented QA Engineer, I have strong experience in both manual and automation testing. I combine my background in various business domains with modern testing tools to ensure end-to-end software quality. By actively using technologies such as Selenium, TestNG/JUnit, Rest-Assured, Postman, Appium, SQL, and Git/GitHub, I conduct comprehensive testing across web, API, and mobile platforms. I am well-versed in Agile/Scrum methodology and take responsibility throughout the sprint for test planning, scenario design, regression management, and defect analysis. With my detail-oriented mindset, analytical problem-solving skills, and strong focus on user experience, I aim to support teams in delivering reliable, scalable, and high-quality products.
