I have never used ConTeXt, but from what I've seen, despite its many differences, a lot is still similar to TeX/LaTeX (e.g. math). Given this, I think it might be easier to create a new derived exporter from ox-latex, and override the parts that differ, instead of creating a new one completely from scratch.

You can see an example in my own https://github.com/zzamboni/ox-leanpub/blob/master/ox-leanpub-markua.el, which uses ox-md as a backend for defining the new ox-markua exporter.

There is also already some documentation at https://orgmode.org/worg/dev/org-export-reference.html

Creating an exporter from scratch is probably easier than you think.
A few years ago I planned a tutorial about this, but another job
happened, then covid happened etc. Now that I finished some big project
taking me a lot of time, I might be tempted to revisit that. Would
there be demand for a DYI Org-exporter-from-scratch tutorial?

Best,
