Alberto Medina worked on the GoogleChromeLabs/ps-analysis-tool repository, focusing on enhancing privacy controls within the user interface. He relocated the Cookies section from Tracking Protection to Site Boundaries, refactoring the UI and updating navigation to improve discoverability and consistency. Using JavaScript and TypeScript, Alberto updated end-to-end tests to ensure stability and alignment with the new UI structure. His work demonstrated strengths in frontend development, refactoring, and test engineering, with disciplined use of Git and pull requests. Over the course of the month, he delivered a targeted feature that addressed user experience and maintainability, though the scope was limited to a single feature.
