Worked on the tweag/rules_haskell repository to enhance the reliability and accuracy of the continuous integration pipeline. Focused on stabilizing the CI workflow by pinning the Windows runner to windows-2022, which addressed compatibility issues with Bazel 7.x and ensured consistent build environments. Improved the testing process by modifying the CI configuration, written in YAML, so that tests for example projects are executed during the test step rather than just being built. Leveraged skills in CI/CD and GitHub Actions to deliver a more dependable feedback loop, reducing flaky test runs and enabling contributors to receive actionable test results more quickly.
