Worked on the SemanticMediaWiki and SemanticResultFormats repositories, focusing on backend PHP development and bug fixing to improve stability and compatibility. Addressed a critical internal error in the JQPlotChart module by resolving missing ResourceLoader references, which enhanced chart rendering reliability and reduced runtime issues for users. Contributed to forward compatibility with MediaWiki 1.43 by replacing deprecated methods and updating related template and media link handling, ensuring the codebase remained aligned with evolving platform standards. Maintained and expanded unit tests to safeguard against regressions, while collaborating with team members to review and refine code quality using PHP and established testing practices.
