How can I also work Rust in on this? I am having way too much fun already and want to push the limits. Open to other ideas, also!

Been programming for some time and usually stick to a language during a project, but often then found myself branching out at some point when a language wasn't delivering for me fully in a certain area.

This current setup is letting me have my cake, eat it, sell it and bake it - all at the same time.
.maybe some heavy filesystem I/O stuff could let me add Rust in? I feel like it might be kind of redundant or superfluous with all the other languages already having so much overlap, but I really really like Rust. It is probably my favorite language of all of them, which was a tough spot to wrestle away from PHP.

I am also open, for the novelty or utility, of adding other languages to this current stack/repository I am in... If you can think of the language + use, feel free to throw it out there on this post!

Like, Go -> Metrics, or Python -> AI, or Node.js -> sockets...

I am past the point of no return, and any useful language would be considered, as I feel confident in my ability (overly confident in my ability) to still properly maintain the repository and pipeline.

Also open to using a language merely for a third party module or something, as well ;)
