Worked on the medusajs/medusa repository to address Windows compatibility issues in the plugin development workflow. Focused on enabling reliable watch-mode publishing for Medusa plugins across platforms, the solution involved invoking Node.js via process.execPath to run yalc, ensuring consistent behavior on Windows, Linux, and macOS. By replacing execFile with process.execPath, the update resolved spawn EFTYPE errors that previously blocked Windows users. The fix was validated through end-to-end testing on Windows 11, with thorough documentation of manual testing steps. This work leveraged TypeScript and full stack development skills to restore cross-platform parity and improve productivity for plugin authors.
