Worked on the Khan/jenkins-jobs repository to migrate Jenkins CI dependency management from Yarn v1 to pnpm v10, focusing on improving build reliability and consistency. Replaced direct yarn calls with a standardized 'make npm_deps' target and introduced a shell script, './dev/tools/run_pkg_script.sh', to centralize package installation and script execution within the CI pipeline. This approach reduced environmental drift and streamlined dependency management, resulting in faster and more deterministic builds. Utilized Groovy, shell scripting, and Make to update Jenkins job configurations, consolidating CI steps under pnpm-based tooling and establishing a more maintainable and robust foundation for ongoing automation.
