Nope, Rawwaad. The binyan is fa33aal, which forms nouns/adjectives with an intensive meaning: "something which does something habitually, repetitively, or to an extreme degree." And r-w-d as a triliteral root means "to lead." So the name Rawwaad kind of has a similar origin to the English name "Richard," although they're not related obviously.

Rawad is supposed to be the name of a person.

Either they expect you to just not use proper nouns like that...or they just haven't accounted for alternate but technically correct answers (because it's still in beta)

That would be " هذا/إنّه رواد سعيد " (that is a happy Rawad )

However, with just these two words, it's always "Rawad is happy"

Naturally In Arabic, it simply doesn't mean what you suggest if the two words are found alone.
