During September 2025, Alex Argri worked on the wavelog/wavelog repository, focusing on backend and frontend development using JavaScript and PHP. He addressed a nuanced issue in the QSO panel where date inputs containing commas caused URL encoding errors, impacting navigation and filtering. Alex implemented a targeted fix that replaced commas in date strings with a URI-safe placeholder before encoding, then restored the original commas after processing. This approach ensured that dates with commas were reliably handled in URL parameters, reducing user-facing errors. The work demonstrated careful attention to edge cases and improved the overall stability of date handling in the application.
