Worked on the kilnfi/public repository to enhance CI/CD deployment stability by updating the GitHub Actions runner configuration. The approach involved replacing the default ubuntu-latest runner with a fixed-resource alternative, fixed-egress-4c-16g, which improved the reliability and predictability of build and deployment processes. Focus was placed on infrastructure configuration and maintainable YAML-based workflows, with an emphasis on traceable changes through detailed commit history. No major bugs were addressed during this period, as the primary objective centered on optimizing deployment environments using DevOps practices, GitHub Actions, and Linux-based CI environments to support more consistent and observable software delivery pipelines.
