Worked on the software-mansion/react-native-reanimated repository, focusing on modernization and stability within the codebase. Addressed a targeted bug in the LayoutAnimationsProxy component by replacing the deprecated ContextContainer::Shared alias with std::shared_ptr<const ContextContainer>, aligning the implementation with current C++ standards and ensuring compatibility with updated libraries. This change improved maintainability and reduced the risk of deprecated APIs affecting downstream users. The work demonstrated a careful approach to future-proofing the project, emphasizing proactive adaptation to evolving dependencies. Utilized C++ and software engineering best practices to support smoother transitions as the library ecosystem advances, prioritizing long-term stability over rapid feature delivery.
