I saw a writing by a friend of mine who uses
as of current. I normally see
as of followed by a specific date, like
as of 2017. I am curious to know if
as of current is a proper usage for
"As of current" is not grammatically correct, and it is not typically used by native speakers. The phrase "as of..." expects a specific date or time. Also, "current" is an adjective and doesn't make sense in this context.
Alternatives would be:
As of [the current date]
As of now
Currently(note that currently is an adverb while current is an adjective. You could say "I currently work as a doctor" but not "I current work as a doctor").
