In October 2025, Andrey Gudym enhanced code quality for the ydb-platform/ydb and ytsaurus/ytsaurus repositories by introducing automated linting for JSON and YAML files within their build systems. Leveraging Make, Makefile, and Python, he developed a clang-format-based JSON linter and a STYLE_YAML macro, integrating these tools into the CI/CD pipeline with a scoped rollout to the taxi/ directory. This approach enabled early detection of formatting inconsistencies and streamlined code reviews, reducing post-merge defects. Andrey’s work established cross-repo linting standards and strengthened CI quality gates, improving maintainability and consistency without requiring major bug fixes during the period.
