Worked on the linkedin/rest.li repository to enhance service discovery and routing reliability for Java-based back-end systems. Developed a method in D2Client to extract cluster names from D2 URIs, improving the accuracy of service identification and routing decisions. Standardized scatter-gather routing logic by introducing and relocating the needScatterGather method to the Client interface, ensuring consistent routing behavior across multiple client implementations. Focused on API development and interface-driven architecture, with careful attention to maintainability and future extensibility. Emphasized unit testing throughout the process, resulting in well-structured, commit-traceable changes that lay the foundation for improved load distribution and observability.
