I've been working on a geospatial library, https://a5geo.org this year. Originally I wrote the code in TypeScript but have since ported to Python and Rust with the aid of Claude Code. The Rust port in particular required zero manual lines of code written by me to get working!

My strategy going forward is one of "Polyglot Mirroring", namely having the codebase in multiple languages in parallel where changes are mirrored using LLMs. I've brainstormed several ways to describe this, and the term I've come up for this is "Polyglot Mirroring". I'm wondering how that sounds to people?

Does anyone have experience with a similar pattern of development?

I've written more about the technique here: https://a5geo.org/docs/ecosystem/polyglot-mirroring

While it might not be for every project, with the cheap availability and quality of LLMs these days, I think it could be a viable technique going forward.
