/ FAQ

Common questions from Chicago clients

Can you start from an existing codebase?

Yes — we run a code audit first, then propose a stabilisation and roadmap plan.

How do you handle data security?

Least-privilege IAM, encrypted at rest and in transit, with auditable change history.

Do you provide ongoing support?

Most clients stay on a retainer for feature work, monitoring and uplift.
