Worked on the prefeiturasp/SME-SIGPAE-FrontEnd repository, focusing on enhancing the robustness of the calendar component using JavaScript and React. Addressed a bug where undefined or missing event data could cause runtime errors by implementing data validation before formatting calendar events. This approach ensured that the calendar component handled edge cases gracefully, improving overall stability and user experience. The work involved updating the index.jsx file to prevent undefined values from breaking the UI, laying the groundwork for future enhancements to the calendar feature. No new features were added during this period, with efforts concentrated on front end bug resolution and reliability.
