Joan Rosero contributed to Proyecto2ORII2024 by addressing backend and frontend issues that improved data integrity and user experience. On the backend, Joan refined the FormCommandService logic to ensure teacher assignments were only applied to specific student mobility event types, reducing incorrect data and simplifying downstream processing. On the frontend, Joan resolved faculty selection mapping errors and enhanced form options with clearer descriptions, preventing misidentification and supporting accurate data entry. These changes, implemented using Java, JavaScript, and React, demonstrated careful risk management and collaboration across teams. Joan’s work focused on targeted bug fixes, reflecting depth in both backend and frontend development.
