I recently needed to trawl through CFPB HMDA data and it was an absolute pleasure to do so. Everything was straightforward and documented in GitHub. I assumed this project was a result of USDS
The CFPB HMDA products were built by the Consumer Financial Protection Bureau's dev team. They've been working on government open source and open data platforms since (I think?) ~2012. (https://github.com/cfpb)
While CFPB is definitely a separate thing from USDS, I'd imagine their end goals are the same: building things that help government better serve citizens. The more dedicated people that take up this mission in public service, the better!
That wasn't us, but I'm glad that it was a good experience for you! Lots of tech in government is getting better these days, and we'd love to have more folks helping up push the state of the art forward.
