Worked on the monta-app/github-workflows repository to enhance CI/CD pipeline reliability by addressing artifact collisions in GitHub Actions matrix workflows. Tackled a recurring issue where hardcoded artifact names led to 409 Conflict errors during concurrent job execution, which caused flaky builds and increased retry overhead. The solution involved implementing unique artifact naming for coverage and build reports using YAML and workflow automation techniques, enabling safe parallel execution across matrix jobs. This change improved the stability of the CI process and accelerated the feedback loop for developers. All modifications were documented, ensuring maintainability and clarity for future workflow enhancements within the repository.
