This paper examines strategies for managing a 270 KLOCCommon Lisp monorepo dedicated to computational fluiddynamics and stochastic optimization. By leveraging CLOS,Macros, and REPL-driven development, we addressed the”crisis of scale” inherent in 1,400 source files. To optimizecloud-native delivery, we implemented a tiered three-phasebuild strategy, reducing build latency by 33–53%. Further-more, refactoring deployment logic achieved an 8x speedupin Kubernetes manifest synchronization. Our findings demon-strate that Common Lisp, combined with disciplined modu-larity, build optimization, and modern DevOps, provides ahighly effective foundation for large-scale applications.
