Cebrail Ergisi enhanced the hmcts/pcs-frontend repository by delivering Pact contract publishing improvements focused on reliability and security. He removed the deprecated pact-node dependency, migrating the workflow to use the pact-broker CLI, and implemented secure command execution with execFile, explicitly managing input and output streams. By improving error handling and logging throughout the publishing pipeline, Cebrail reduced the risk of failures and increased CI/CD robustness. He also adjusted the pull request workflow to align with evolving tooling requirements. This work demonstrated practical application of Node.js, TypeScript, and CI/CD skills, addressing technical debt and strengthening contract testing infrastructure within the project.
