It'd be great to read about all the things this internal DevX org has been able to improve after some time.
Internal developer experience is extremely important. One codebase I worked on used to have a 24-hour, nondeterministic CI run. A teammate brought that time down to ~45 minutes (it's a big codebase with a ton of tests) and made it deterministic. Everything got better:
* Faster turnaround time for external contributions (it's OSS)
* Ability to be relied on to get a critical fix in and tested in under an hour
* Much faster local build times
* Removed reliance on some old busted internal infrastructure so we could use much better, different infrastructure, and make the build/test runs the same across any OS rather than rely on windows so much
* Everyone was happier in general
If we could have gotten a full CI run down from 45 minutes to 15 minutes, that'd be great. And there was still quite a lot of technical debt in the tests themselves, since they should be able to run a lot faster than they did. But even with that in mind, the difference was night and day.
