Worked on the UbiqueInnovation/workflows-backend repository to modernize and stabilize CI/CD pipelines over a two-month period. Focused on upgrading Docker login workflows by adopting docker/login-action@v3 and standardizing authentication using registry-based logins, which enabled support for multiple registries and improved deployment reliability. Addressed critical issues with secret mapping in Docker image workflows, preventing authentication failures and reducing build-time errors. Additionally, standardized YAML indentation across all GitHub Actions workflow files, enhancing readability and maintainability of CI configurations. Demonstrated expertise in CI/CD, Docker, GitHub Actions, and YAML, with an emphasis on incremental refactoring and robust secret management for scalable deployments.
