Hi,
i'm a software quality engineer with 4 years industry experience in software testing.
I'm especially specialized in Rest API, Node.Js, javascript, json object handling and so on.
Not sure about the project details, but from my experience, if you were to verify the json at a scalable way, I may help you to convert to xml and verify through XSLT on a very programmatic way.
that would mean your test automation will be very scalable in a way that it don't really do manual verification, and instead with a neat way you could identify the result with logics.
Of course, the solution may be different if your problem is different.
Hire me, i can provide you my linkedin profile to verify further on my portfolio.
