I coincidentally worked on something similar but I kept closer to the SQL standard. It grew out of business cases where you don't have strongly typed data to act on.

I more or less adopted the syntax from dumbql (https://github.com/tomakado/dumbql) and started off with a peg parser using ohm.js. As I started benchmarking I realized how slow it was and started looking for "fast paths" using regex. I ultimately resorted to a recursive descent parser similar to Elo. At that stage I already had a lot of tests and api in place, so I was able to get a lot of help from Claude.
