Worked on the LifeSG/react-design-system repository to enhance security and consistency by managing Node.js runtime versions. Addressed vulnerabilities and reduced environment drift by upgrading Node.js to version 22.15.0 and aligning the .nvmrc file to 22.13, ensuring parity between development and production environments. Leveraged skills in Node.js, Shell scripting, and version management to standardize runtime configurations, which contributed to smoother CI/CD onboarding and improved overall stability. Maintained clear traceability through well-documented commits linked to the relevant issue, supporting auditability and code review processes. The work focused on proactive vulnerability remediation rather than reactive bug fixing during this period.
