I build reliable web application test coverage through manual testing, Playwright automation, and CI/CD validation.

What I'm looking for

I'm looking for QA engineering work where I can strengthen web application quality through manual testing, Playwright automation, CI/CD validation, API testing, and data-focused release support in Agile teams.

I've delivered quality assurance across web applications at NTT Data, a confidential mail web application project, and Advancio, supporting Agile releases through manual testing, regression coverage, data validation, and structured defect management.

At NTT Data, I designed and executed 150+ manual test cases for an Azure-deployed web application, authored test plans and release checklists, and supported 3+ production releases with zero critical post-release defects. I also validated CI/CD deployments using CMD and SQL queries and monitored business workflows in Camunda.

I've built an end-to-end Playwright and TypeScript automation framework for SauceDemo using the Page Object Model, GitHub Actions, and Allure reporting. My work also includes API testing with Postman, SQL validation across multiple database environments, Jira defect triage, and pixel-perfect UI validation.

I'm a Computer Systems Engineering graduate who enjoys turning test cases into automation-ready flows and helping teams release dependable software.
