Worked on the kvcache-ai/Mooncake repository to enhance code quality governance and deployment guidance by delivering two key features within a month. Integrated code coverage reporting into the CI pipeline, wiring coverage tools and flags using Bash and YAML, and generating LCOV reports to improve visibility into testing effectiveness. Upgraded the Codecov action and added coverage status checks for faster pull request validation. Additionally, updated the Chinese build guide with Docker deployment instructions, resolving path issues to provide clearer guidance for users. Focused on CI/CD, DevOps, and documentation, these contributions improved developer velocity and customer-facing reliability without introducing new bugs.
