It does get a little more nuanced than that since he made Ancient specifically to handle the Master System/GG versions of Sonic, and they still dabble in development from time to time, (a fact cleverly concealed in the linked article, which is a great read btw) so technically he's also a dev, but yeah, didn't have much to do with EO past music.
He's a composer
At least Nintendo still make amazing games. You havent made awesome music since the Actraiser days. Etrian Odyssey music is good, but you are not anymore on your Streets of Rage level.
