Worked on the felleslosninger/github-workflows repository to enhance Docker build processes and simplify CI/CD workflows. Focused on organizing test resources through folder-based management and refactored build steps to streamline GitHub Actions inputs, all implemented using YAML and Docker. By removing unnecessary folder inputs and improving resource organization, the changes reduced configuration drift and maintenance overhead. This approach led to faster and more reliable Docker image builds and deployments, supporting better workflow maintainability. The work demonstrated a practical application of CI/CD and DevOps principles, emphasizing traceability and accountability through clear commit history and structured workflow improvements within the repository.
