Example Concept: A multi-stage CI pipeline for a large monorepo should be designed to include distinct stages such as linting, unit testing, integration testing, and deployment. Each stage can be parallelized to handle different modules or components independently, using caching mechanisms to speed up repeated tasks. Tools like Bazel or Nx can be used to manage dependencies and build processes efficiently, while CI platforms like Jenkins, GitLab CI, or GitHub Actions can orchestrate the pipeline stages. This approach ensures that changes are validated quickly and reliably, reducing bottlenecks and improving feedback loops.
