Why Sonnet Code for QA Testing & Automation

The bar we hold ourselves to.

Senior only

Every engineer we put on your work has 5+ years shipping production code. No rotations out, no bait-and-switch.

Measured, not promised

Performance budgets, observability, and evaluation metrics are part of the build — not things we add after you ask.

Honest scoping

We'll tell you when this is the wrong tool for the job. The fastest way to lose a client is to ship the wrong thing.
