In December 2024, Mate Strysewske developed multilingual validation messaging for AEFI reports within the SORMAS-Foundation/SORMAS-Project repository, focusing on improving data completeness and accuracy in pharmacovigilance reporting. He implemented internationalization and localization updates using Crowdin, working primarily with properties files to ensure prompts for required fields—such as suspect vaccines and adverse events—were available across multiple languages. The work addressed the needs of a diverse user base by enhancing translation coverage and aligning validation logic with multilingual requirements. While the scope was limited to one feature, the changes contributed depth by strengthening both data quality and user experience in AEFI reporting.
