Worked on security hardening and automation for the credebl/platform and credebl/studio repositories, focusing on reducing vulnerabilities and improving build reliability. Upgraded Node.js and standardized OpenSSL versions across multiple Dockerfiles, addressing known security issues and ensuring compliance with best practices. Implemented automated dependency management using Dependabot, streamlining updates for npm, Docker, and GitHub Actions. Enhanced startup stability by correcting Dockerfile commands and refreshed lockfiles to guarantee reproducible builds. Used JavaScript, TypeScript, and YAML to deliver these improvements, applying skills in containerization, DevOps, and security auditing to establish a foundation for ongoing maintenance and secure, stable software delivery.
