During November 2024, Maria Paula Cardona Arévalo enhanced the InnovaTech-arquitectura/back-admin repository by optimizing image upload functionality within the PublicationController. She implemented logic in Java and Spring Boot to ensure MinIO storage is only invoked when a new image is provided in the data transfer object, reducing unnecessary storage operations and conserving resources. To improve observability and debugging, she added a console log path for cases where no new image is uploaded. This targeted backend development addressed a specific efficiency issue, demonstrating a focused approach to resource management and maintainability, though the scope of work was limited to a single feature.
