Worked on modernizing the CI/CD pipeline for the hawk-ai-aml/github-actions repository by upgrading the Node.js runtime in the build-reactjs.yaml workflow. Focused on enhancing both security and performance, the update moved the Node.js version from 18.x to ^22.12.0, ensuring the CI process leveraged the latest improvements without introducing risk to production builds. Employed GitHub Actions and YAML to implement and document the change, maintaining traceability through targeted commits. The work emphasized reliability and auditability, with all modifications confined to the build workflow. No bugs were addressed during this period, as the primary focus remained on feature-driven CI enhancements.
