You send us access to the code or the build. We send back a plain-language report: what is broken, what is fine, and what it costs to fix.
No meetings marathon. You give access, we do the work, you get the report.
It is best. If you do not have it, we audit the installed build and tell you how to recover the code from the previous developer.
We audit those too and say honestly whether it is worth fixing as is or moving to native code.
No. The report separates what must be fixed from what can wait, and you choose what to do.
