How One Engineer Reduced a Monorepo CI Pipeline to 8 Minutes

Episode 40 of The Software Engineering Podcast dives into monorepo CI optimization. Lucas and Luna explore how a single engineer at a mid-sized tech company slashed continuous integration from 45 minutes to under 8 minutes by implementing incremental builds and dependency caching. They break down the specific techniques: Bazel-style action caching, remote caching with a shared Redis store, and a custom build graph that only rebuilds changed packages. The episode covers the before-and-after metrics, the hidden cost of full rebuilds, and how the team avoided common pitfalls like cache invalidation bugs and flaky test pollution. A concrete case study for anyone stuck with a slow monorepo pipeline. #Monorepo #CI #BuildOptimization #ContinuousIntegration #Bazel #IncrementalBuilds #DependencyCaching #Redis #BuildGraph #SoftwareEngineering #DevOps #Performance #CacheInvalidation #EngineeringCulture #TechPodcast #Technology #FexingoBusiness #BusinessPodcast Keep every episode free: buymeacoffee.com/fexingo
