Worked on CopilotKit/CopilotKit to enhance cross-platform build script compatibility, focusing on Windows environments. Addressed the challenge of Unix-specific shell commands in package.json by replacing them with Node.js-based alternatives, ensuring that build and development scripts functioned reliably across different operating systems. This approach eliminated dependencies on Unix-only commands, reducing environment-related build failures and streamlining both onboarding and continuous integration processes. Utilized skills in Node.js, npm, and cross-platform development to achieve parity in core build tasks, ultimately improving the reliability of development workflows and accelerating feature delivery for teams working in diverse environments. No bug fixes were recorded during this period.
