I’d like to work on this issue because maintaining consistent runtime environments is important for project stability and developer experience. Adding the engines field to package.json helps ensure contributors and deployments use compatible Node.js and package manager versions, reducing environment-related issues and improving reliability across the project.

I have experience working with JavaScript/TypeScript projects, Node.js applications, and package management workflows as a full-stack developer. I’ve worked with project configuration files, dependency management, CI/CD environments, and backend setups where version consistency is critical for smooth development and deployment.

This issue is a good fit for me because it involves improving project maintainability and development workflow standards. I’m comfortable reviewing existing configurations, understanding compatibility requirements, and implementing clean, standards-based updates to the project setup.
