Worked on stabilizing and enhancing CI/CD reliability for the espressif/esp-matter repository by migrating the build infrastructure to the PN Jenkins server. Addressed a critical pipeline issue by updating the Jenkinsfile and CI configuration, shifting build agents from the legacy 'master' node to a dedicated 'build' node, and adding a 'build' label to the Docker agent configuration. This approach reduced infrastructure drift and improved traceability, ensuring that Jenkins jobs consistently run on the intended server. Leveraged Groovy and Jenkins expertise to adapt the pipeline, laying the foundation for scalable and maintainable CI/CD processes across future infrastructure migrations.
