Worked on greenbone/gvm-libs and greenbone/actions, focusing on enhancing reliability and maintainability through targeted improvements. In gvm-libs, migrated the unit testing environment to use the Debian cgreen package within the devcontainer, ensured libcgreen development packages were available in Docker images, and refined code coverage accuracy by adding exclusions to gcovr. Improved build configuration readability by standardizing CMakeLists formatting. In greenbone/actions, addressed Unicode reporting by resetting the column counter per line for precise detection and introduced a command line option to scan individual files for hidden Unicode characters. Utilized Python, CMake, and Dockerfile, emphasizing testing, debugging, and build configuration.
