Worked on the Staffbase/gha-workflows repository to enhance Docker build processes by introducing architecture-aware builds with ARM (linux/arm64) support and enforcing single-platform deployment. Leveraged YAML and Markdown to update CI/CD workflows and documentation, ensuring clarity and maintainability throughout the pipeline. Refactored GitHub Actions workflows to simplify runner architecture variable usage and removed misleading architecture names from job titles, aligning with a single-architecture policy. Improved test reliability by eliminating redundant checks and updating test logic. Updated the README to document new architecture options, laying the foundation for future multi-architecture capabilities while maintaining a focus on clear communication and collaboration.
