What I'm looking for

I’m seeking a mid-level Manual Tester or Playwright Automation Engineer role to drive quality at scale—building stable automation, strengthening manual/API coverage, integrating CI/CD, and reducing regressions and flakes while supporting fast, confident releases.

I’m a QA Engineer with 7+ years delivering zero-defect releases across Web, Android, and iOS in the Healthcare domain. I focus on quality at scale—reducing manual regression effort by 40% and flaky test rates by 30% through Playwright (JavaScript) and Selenium automation.

In my latest role as Senior Software Engineer — QA at Cross Country Infotech, I maintained a 100% clean-release record across 5+ sprint releases for a healthcare job portal. I used risk-based test strategy to cover 10+ workflows and drove releases forward with clear release sign-off in JIRA.

Automation is where I bring stability and speed. I authored production-grade Playwright (JS) test suites using POM, parallel execution, network interception (page.route()), and storageState authentication, then integrated everything into Azure DevOps CI/CD (azure-pipelines.yml) to publish HTML reports as artifacts.

I also bring a strong manual and API testing foundation, including Functional, Regression, Smoke/Sanity, UAT, integration testing, and Swagger/OpenAPI-equivalent contract testing via Postman. From Trace Viewer and screenshot-on-failure to structured retries, I accelerate root cause analysis and help teams ship with confidence.
