During a two-month period, Zhuhao Zhu developed Slack-enabled messaging and notification features for the Betca TPV suite, working across the miw-upm/betca-tpv-angular and miw-upm/betca-tpv-core repositories. He implemented a Slack publishing UI in Angular, allowing users to compose and send messages with level-based selection, and established backend services in Java with Spring Boot to support Slack notifications for cashier closings. His work included API development, integration testing with WireMock, and configuration management using Docker. By focusing on cross-repo integration and test automation, Zhuhao delivered scalable, real-time communication features that improved operational visibility and streamlined team workflows.
