Worked on the seek-oss/skuba repository to optimize production Docker images by refining how dependencies are managed during builds. Updated Dockerfiles to use the 'pnpm prune --prod' command instead of 'pnpm install --prod', ensuring that only production dependencies are included and development dependencies are excluded from final images. This approach reduced image size and attack surface, aligning with production hardening goals. Added automated tests in JavaScript and TypeScript to validate the new build behavior and confirm that Dockerfiles are patched correctly. Demonstrated skills in CI/CD, Docker, and Node.js while focusing on reliability and efficiency in deployment workflows.
