During October 2025, Mridul focused on enhancing the reliability and efficiency of the econ-ark/HARK repository’s continuous integration processes. He implemented parallelized test execution using pytest and integrated coverage reporting, leveraging Python and YAML to improve feedback speed and test visibility. Additionally, Mridul simplified the GitHub Actions workflow by removing the pull_request trigger, allowing CI runs to be scheduled or manually dispatched, which reduced workflow complexity and maintenance overhead. His work demonstrated a strong grasp of CI/CD best practices and testing methodologies, delivering targeted improvements that support more robust releases and a streamlined development process for the HARK module.
