Worked on the SemanticMediaWiki/SemanticMediaWiki repository, focusing on improving the reliability of namespace handling in PHP back end code. Addressed a critical bug by refactoring the NamespaceManager to use array_merge instead of the addition operator when merging content namespaces, ensuring accurate configuration and reducing the risk of misconfigurations. This targeted debugging effort enhanced the stability of content search and laid groundwork for future improvements in namespace management. Demonstrated strong skills in PHP array handling and back end development, delivering a solution that improved both the accuracy of namespace configuration and the overall reliability of search functionality within the project.
