Worked on modernizing the CI/CD pipeline for the Dataflux-U-nidos/Backend repository, focusing on improving test reliability and release safety. Introduced a Bun-based testing workflow using GitHub Actions, replacing the legacy process to streamline continuous integration. Enhanced the pipeline with AWS credential management, Docker image tagging, and environment-driven testing, enabling more robust and flexible deployments. Added a test placeholder in the domain entities to support future test expansion and maintain code organization. Leveraged TypeScript, YAML, and shell scripting to implement these changes, emphasizing automation and maintainability. The work addressed core DevOps challenges and laid groundwork for faster, safer releases.
