Lisa Kirchhofer focused on enhancing the data table filtering experience in the porscheinformatik/material-addons repository during June 2025. She developed a feature that introduced a delete-filter action, a clear-all filters button, and a badge displaying the number of active filters, all aimed at improving data exploration for users. Her technical approach involved making targeted updates to HTML and SCSS to ensure seamless integration with the existing Material Design system and maintain styling consistency. Working primarily with Angular, TypeScript, and SCSS, Lisa delivered a well-scoped feature that addressed a specific user need, demonstrating depth in front-end development and design integration.
