New Mistake Everyday - Word Choice - Writer and Known

Yesterday, I made a comment on the legal case submitted by Andrea Hirata via Twitter. I said to my friend, "I think I know the writer. He is also known as a senior copywriter in a multinational ad agency." At the moment, I feel that my sentence was amateurish. Could this sentence be a primo revision, "I think I know the author. He is also recognized as a senior copywriter in a multinational ad agency."?
