Worked on enhancing data processing performance in the web-infra-dev/rsdoctor repository by refactoring the loader rule. The approach involved replacing the existing map and reduce logic with flatMap, resulting in faster and more scalable data loading workflows. This change improved throughput and reduced latency for loader-driven processes while maintaining overall pipeline stability. The work was implemented using TypeScript and focused on performance optimization and code refactoring within a production environment. Throughout the process, careful change management was applied to minimize risk, ensuring that the optimization delivered measurable efficiency gains without introducing instability or regressions into the existing codebase.
