Electron.js Integration Advice Needed

I'm developing a local app using Electron.js, React.js, and a Node.js backend. I need expert advice on two main functionalities: how to start Node.js when the app opens, and how to package Node.js inside the Electron app to make it self-contained. The final goal is to deploy this app on Windows.

Ideal Skills:
- Deep understanding of Electron.js
- Proficiency in Node.js and React.js
- Experience in packaging apps for Windows and macos

Please note that my budget for this consultation is $10.
