Worked on stabilizing API deployment routing in the bella-openapi repository by addressing a critical bug in the QueueAdaptor model naming logic. Using Java and backend development skills, reverted changes that had transferred model_name to deploy_name, which previously caused incorrect model selection and misrouted deployments. Carefully removed deployName-based model selection to ensure deployment decisions consistently align with the intended model, thereby reducing the risk of routing errors in production. Maintained a clear and minimal commit history to support future maintenance and audits, demonstrating strong regression discipline, thorough code review, and precise change-tracking throughout the process to enhance deployment reliability.
