Has anyone built an enterprise-level project using Claude Code?

I’m curious to hear from people who have real-world experience with Claude Code. Has anyone here built or shipped an enterprise-level project using Claude Code as a core part of their development workflow? I’m particularly interested in things like: • Large or complex codebases • Production-grade systems • Long-term maintainability • How it performs compared to other coding assistants in real projects If you’ve used it beyond small experiments or prototypes, I’d really appreciate hearing what worked well, what didn’t, and whether you’d recommend it for serious, production use.
