I made this tool to sift through all the who's hiring posts. You'll need node / npm, but it works locally. It includes 2019 data. In the future, I hope to include all who's hiring posts with better graphs to visualize it.

You can download it and play with it from here: https://github.com/vishaldpatel/jobstats

And if you do, I'd love feedback! Including code feedback. There's some stuff that I haven't followed.

Thank you! - V
