Yes, I use it all day at work for troubleshooting unfamiliar code in a giant monorepo, and writing terraform / k8s files. Claude code is easily a 20x time multiplier for investigating things I'm not fluent in, and probably 3x for writing new stuff.
Note that I'm not vibe coding. Everything is peer reviewed and I understand what it's all doing. Many people seem to assume if you use an AI then you're just vibe coding, that isn't the case.
