Aurelien worked on the tamagui/tamagui repository, focusing on improving cross-platform styling consistency in React Native applications. He addressed compatibility issues introduced by React Native 0.76 by modifying the core styling pipeline to support web-style CSS properties such as boxShadow and filter on native builds. This involved removing these properties from the skip list, ensuring they rendered correctly across both web and native environments. Using TypeScript and leveraging his frontend and web development expertise, Aurelien delivered a targeted fix that minimized surface area, reduced UI regressions, and enabled faster review cycles, demonstrating a thoughtful approach to maintaining styling parity.
