We are passionate about software quality, repeatability, testability and maintainability. When we need clarity, we go to the product customers, perhaps a user, and talk to them until we get it right. We understand the challenges associated with operating a large-scale system in production, and our designs and implementations reflect that understanding.When we are wrong, we are happy to learn something. We build software quickly, but properly so that we don't have to go back to it later. We know what "unit tests" are and don't implement software without them.
