Frequently asked questions

Can you take over an existing codebase?

Yes. We start with a code audit, document what we find and propose a safe plan.

Will we own the source code?

Yes. After final payment the code and intellectual property are fully yours.

Do you write documentation?

Every API and system ships with documentation so your team or future partners can work with it.
