I was an early employee at CircleCI. I have used, in anger, nearly every CI system that has ever existed. Jenkins, Travis, CircleCI, Semaphore, Drone, Concourse, Wercker (remember Wercker?), TeamCity, Bamboo, GitLab CI, CodeBuild, and probably a half dozen others I’ve mercifully forgotten. I have mass-tested these systems so that you don’t have to, and I have the scars to show for it, and I am her
