Worked on the Crypto-TII/claasp repository to enhance the reliability and observability of the CI/CD pipeline, focusing on backend infrastructure rather than user-facing features. Addressed a persistent issue by configuring coverage reporting for SonarCloud, ensuring that test coverage signals were complete and actionable. Utilized CI/CD configuration skills and worked primarily with cfg files to implement these changes. Temporarily disabled an unstable doctest job to reduce pipeline flakiness during debugging, maintaining traceability through well-documented commits. The work enabled faster and safer releases by improving the stability of automated testing and coverage reporting, supporting ongoing quality assurance for the project.
