Automating CI/CD for ChromeOS at Google. A software engineer, Freemason, and naturalist. I relish fine foods and puns.
The Azeron and reWASD software are Windows only, unfortunately.

If you’re OK with stepping away from a standard keyboard, I have an Azeron Cyborg that I use for most of my games. Paired with reWASD, it is infinitely customizable. It’s a bit pricey, but I love having a thumbstick in the mix. Not quite what you’re looking for, but maybe it provides some inspiration?
