Frequently asked questions

Can you work on firmware written by another team?

Yes. We start with a code and architecture review, then fix the highest-risk issues before adding features.

Do you support safety-critical standards?

We follow structured practices, but we do not claim certification for safety-critical standards. For those projects we work alongside your certified safety process.
