Software Engineering Tester with over 4 years of experience in designing, implementing, and executing tests.

At Scalefocus, I author test analyses and case suites for a material testing platform, tracing coverage to product requirements and technical specifications. I also implement API tests in Jest and maintain Cypress UI and end-to-end suites.

For an application for mobile data syncing, I designed an automation testing framework and built iOS test suites with Appium and Selenium. At Endava, I developed API automation frameworks for a cargo shipping compliance platform and tested risk detection pipelines.

I use Claude and Claude Code to support test case generation and analysis while maintaining traceability. I also teach games development with Scratch at Coding Giants and previously taught Java programming fundamentals at Meerkat.
