QA Automation Engineer at Flash who refactored E2E testing to Playwright and Appium.

At Flash, I built and maintained end-to-end test suites in C# with Ranorex and TypeScript with Playwright and Appium, covering desktop, mobile, and hardware interfaces. I refactored the framework to Playwright and Appium to improve Apple ecosystem compatibility and maintainability.

As a Software Test Engineer, I designed API test suites for a high-traffic SMS SaaS platform and integrated automated tests into CI/CD pipelines. I also tested API reliability and security under peak concurrent load.

At Newtech, I moved from Software QA Analyst to Software QA Project Manager, authoring test plans and directing manual testing against acceptance criteria. Earlier, as a Linux System Administrator at Liquid Web, I maintained Linux hosting environments and deployed WordPress updates.
