Worked on the microsoft/playwright repository to enhance the clarity of image-diff visualizations in the HTML reporter. Focused on aligning size labels within the screenshot difference slider, ensuring that expected and actual dimensions are clearly displayed for users interpreting test diffs. Addressed a UI alignment bug that previously caused confusion, improving the overall readability and reliability of visual validations. Utilized React and TypeScript to implement these front end changes, applying HTML and CSS alignment techniques to refine the user interface. Demonstrated attention to detail and commit-based traceability while collaborating across teams to deliver targeted improvements within a major open source project.
