Worked on stabilizing OSS-Fuzz integration for the google/oss-fuzz repository, focusing on the OpenBabel test suite. Addressed a build stability issue by removing deprecated std::random usage in test files, ensuring compatibility with current C++ standards and reducing continuous integration build failures. This change improved the reliability of test runs and enhanced the experience for downstream contributors. Utilized C++ and shell scripting to update build scripts and maintain test infrastructure. The work centered on bug fixing rather than feature development, demonstrating attention to detail in maintaining open source test environments and aligning legacy code with modern build and language standards.
