During March 2026, Dragon contributed to the thorvg/thorvg repository by refactoring the C++ codebase to remove unused fstream imports from two source files. This targeted cleanup reduced unnecessary dependencies, resulting in faster compilation times and a more maintainable project structure. Dragon applied clean code practices and code optimization techniques to streamline the build process, lowering the risk of future build issues and simplifying ongoing maintenance. The work was tracked in a single, well-documented commit, ensuring traceability and ease of rollback if needed. While the scope was focused, the changes improved the overall quality and efficiency of the codebase.
