Worked on the webdriverio/webdriverio repository to enhance accessibility testing workflows and improve code reliability. Over two months, delivered a targeted bug fix in TypeScript that stabilized accessibility handler command binding by ensuring original functions were preserved when overwriting element commands, reducing runtime errors and improving stability. Later, implemented per-test accessibility tracking by forwarding test names through scanning functions, enabling granular accessibility reporting and reducing investigation time for failing tests. Maintained code quality with ESLint fixes and expanded unit test coverage to support the new tracking path. Demonstrated proficiency in TypeScript, WebdriverIO, accessibility testing, and full stack development practices.
