FAQ

How do you avoid breaking existing functionality?

We write tests first, refactor in small steps, and verify at each stage.

Can you work on code we didn’t write?

Yes — we specialize in “rescuing” other people’s code.

Do you add tests?

Yes — we believe refactoring without tests is dangerous.

How long does refactoring take?

Small module: 2–5 days. Large system: 2–6 weeks.
