TIL: "Sentry Zero"
This was a big project including code refactoring, increasing test coverage, and bringing better release processes to our product.
As the founder, I wasn't involved, but it was great to watch. It was the smoothest transition of that size that I have ever seen inside a product company.
Must be nice to have that kind of support from management. Usually it's "what will $expensive_refactor bring to our clients, right now?"
