Worked on the dfinity/new-motoko-base repository to enhance supply chain security by implementing a policy that enforces a minimum seven-day release age for npm packages. This was achieved through the addition of an .npmrc configuration, leveraging plaintext configuration management and DevOps practices to prevent rapid package updates that could introduce vulnerabilities. The approach improved release governance, auditability, and compliance with security best practices, ensuring that only thoroughly vetted packages are deployed. By focusing on repository configuration and Node/npm release workflows, the work contributed to a stronger security posture and clearer release cadence across the project during the development period.
