LOL, that guy. Sean S Cunningham got incredibly lucky that the franchise hit. Hated the hockey mask? It's the definitive Jason. It's the reason he's still around. He owes Steve Miner a lot. Even though New Kids and Deep Star Six were alright it's mostly because of Miner that people really care who he is anymore since, good and bad (mostly bad), it's the sequels with Jason that keep him relevant.
Otherwise he's just the guy that made a derivative work based on a bad Mario Bava film in a long line of filmmakers (who never got curious name recognition) who were employed by reactionary studios trying to cash in on the success of John Carpenter's much better film.
