Worked on modernizing CI/CD pipelines for the epam/edp-tekton repository by upgrading Node.js versions and standardizing build commands to improve consistency and maintainability. Focused on pipeline management using yaml, the developer replaced the previous 'npm run build:prod' command with a unified 'npm run build' across multiple pipeline definitions. This approach reduced operational risk and enabled the use of newer Node.js features, resulting in faster and more stable builds. The work emphasized DevOps best practices, ensuring that the pipelines are easier to manage and update. No major bugs were addressed during this period, with efforts concentrated on feature enhancement.
