What I'm looking for

I’m looking for a Senior QA automation role where I can expand dependable E2E/API coverage, deepen CI/CD integration, and work closely with Agile teams to ship high-quality software.

I’m a Senior Quality Assurance Engineer with 10+ years delivering both manual and automated testing across web and API applications. I build and maintain end-to-end (E2E) and API test coverage that improves confidence in releases while keeping teams aligned on clear acceptance criteria.

In recent roles, I’ve developed automated E2E frameworks using JavaScript and Playwright, and I’ve partnered with engineering teams to validate integrations through API and frontend testing. I’m hands-on with log analysis and troubleshooting to pinpoint root causes, then support defect identification and resolution through disciplined bug reporting and tracking.

I also bring strong automation depth from Java-based stacks—creating E2E and API suites with Selenium WebDriver and REST Assured, integrating automated execution into CI/CD pipelines via Jenkins. I’ve implemented BDD with Cucumber to bridge technical and business requirements, and I’ve managed testing workflows using tools like Jira and Qase.

Beyond automation, I’ve performed exploratory, regression, and accessibility testing, including cross-browser validation using Sauce Labs. I aim to bring structured quality practices to Agile/Scrum teams—strengthening test documentation, improving maintainability, and making quality a shared outcome from planning to production.
