During November 2024, Joshua focused on stabilizing data update flows within the Backbase/stream-services repository, addressing a critical bug that affected arrangement update integrity. He corrected the invocation of the putArrangementById method to ensure the internal arrangement ID, rather than the external ID, was consistently used across ArrangementService and related components. This backend development work, implemented in Java and leveraging Spring Boot, required careful API integration and repository alignment to propagate the correct identifiers throughout core services. Joshua’s targeted fix improved data consistency and reduced the risk of incorrect updates, enhancing the reliability of arrangement updates across dependent systems.
