I'm a Software Development Engineer in Test (SDET) passionate about building reliable, scalable, and maintainable test automation solutions. I specialize in Java, Selenium, Playwright, TestNG, Cucumber, API Testing, and CI/CD, with hands-on experience in designing automated tests and improving software quality across the development lifecycle.

With 3+ years of experience in QA and Automation Testing, I bring a developer mindset to testing — writing clean automation code, building reusable frameworks, integrating tests into CI/CD pipelines, and collaborating closely with developers to deliver high-quality software.
