Nit: there's a link to cue.dev at the very end of the article, I would put that up top, along with a brief description of what it provides either at the very beginning or when cue is first mentioned.
Ahh yeah I forgot these two things! I've now added them when CUE is first mentioned in "The system architecture" section, although not at the very beginning as I was trying to give an overview of the project and why I started building my custom solution first
