During November 2024, contributed backend development work to the InnovaTech-arquitectura/back-admin repository, focusing on optimizing image handling within the PublicationController. Implemented a feature using Java and Spring Boot that ensures MinIO storage is only invoked when a new image is provided in the data transfer object, thereby reducing unnecessary storage operations and conserving resources. Enhanced system observability by adding console output for cases where no new image is uploaded, supporting easier debugging and monitoring. The work demonstrated attention to efficient resource management and clear change traceability, leveraging REST API design principles to streamline the publication image upload process.
