In March 2025, Josh Hilliard modernized the CI/CD pipeline for the agglayer/agglayer repository by developing a modular, reusable end-to-end testing workflow. He refactored the existing CI process to replace direct Kurtosis CDK tests with a shared E2E workflow, streamlining test execution and reducing overall pipeline complexity. This approach centralized end-to-end testing, enabling faster feedback cycles and easier maintenance across multiple repositories. Josh utilized GitHub Actions and YAML to implement the new workflow, focusing on maintainability and cross-repo code reuse. The work demonstrated a thoughtful approach to CI/CD design, emphasizing modularity and long-term scalability for the agglayer project.
