So I had this client a couple of years back.
They wanted to set up a platform to help companies with their GDPR (privacy) implementation.
So they came to me and asked me if I could build this for them, of course I could.
Except, they really wanted to build it using a no-code platform which I won't mention here, but we'll call it X.
With X, you could drag 'n drop web interfaces, a database and business logic.
I'd never heard of X, but I was willing to learn and their technical guy and I went for a training day (they paid for me, but I didn't charge my hours).
