Sonia Hussain worked on the alphagov/government-frontend repository, focusing on frontend asset management and UI clarity. She removed the outdated HMRC banner, dated 29.08.24, along with its associated tests, ensuring the interface remained consistent with current branding and reducing the risk of stale content. Sonia approached this by safely deprecating obsolete assets and updating related configuration files, using erb, ruby, and yml to maintain codebase integrity. Her work streamlined the test suite and reduced maintenance overhead. While the scope was limited to a single feature over one month, the changes contributed to a cleaner, more maintainable frontend codebase.
