Don't call them rockstars - call them "resume-driven developers."
We had one on our team in the past.
A bunch of microservices built on an in-house RPC framework he wrote, RabbitMQ, half-baked "monads" in an OOP language, esoteric naming, and no comments (the code should be self-documenting!), no docs.
Management adored him.
Once we started to grow, the problems started to appear: bad orchestration, uninformative logs full of PII, poor error handling, edge cases that were nearly impossible to fix within the existing abstractions, dependency hell, etc.
At that point, he moved on.
It took years and many hundreds of pull requests to clean it up.
