Worked on the vdaas/vald repository to refactor the Load Balancer gRPC handler, focusing on improving maintainability and extensibility. The approach involved modularizing the handler by dividing it into dedicated files for each operation, including flush, insert, search, update, upsert, and remove. This restructuring reduced cross-file dependencies and aligned the codebase with existing gRPC endpoints, making future feature delivery and testing more efficient. Utilizing Go and gRPC, the work emphasized backend development and modular design principles, laying a foundation for safer production deployments and clearer subsystem ownership within the load balancing workflow, while enabling easier ongoing maintenance and enhancements.
