Worked on the privacy-tech-lab/gpc-web-crawler repository to deliver a security and performance upgrade by updating the Rest API runtime Docker base image from Node.js 16 to Node.js 18. This change focused on containerization and DevOps practices, ensuring improved security posture and better runtime support without altering the application logic. The upgrade enhanced deployment safety and maintainability, while also preparing the codebase for future Node.js 18-specific features and vulnerability remediation. The work demonstrated proficiency in Dockerfile management, version control, and CI/CD readiness, emphasizing traceable, incremental improvements to the infrastructure layer rather than direct application feature development or bug fixes.
