PROFILE
Bernd Hacker
Contributed to the Porsche Design System repository by developing and refining core UI components, with a focus on the table and scroller modules. Enhanced accessibility and visual consistency through targeted bug fixes and extended component props, while improving documentation and test coverage using TypeScript, CSS, and JavaScript. Refactored component logic for type safety and performance, streamlined styles to reduce CSS bloat, and standardized snapshot and visual regression testing for reliability. Prioritized maintainability by removing deprecated patterns and redundant code, ensuring efficient builds and consistent server-side rendering. The work emphasized robust front-end development practices and sustainable codebase evolution over three months.
