Developed a Node.js version compatibility check for the openai/codex repository, focusing on improving deployment reliability and user experience. The feature automatically parses the required Node.js version from package.json and validates the runtime environment before execution, preventing misconfigurations and runtime errors. This pre-execution validation was implemented using JavaScript and leveraged CLI development skills, ensuring that the application only runs when the correct Node.js version is present. By introducing this automated check, the work aligned project requirements with actual deployments, reduced support overhead, and contributed to smoother workflows. No major bugs were addressed during this period, with efforts centered on feature delivery.
