First seen- Season one, episode 1 Ryan starts off as the soft-spoken temp who gets a little used and abused by his superiors.

Last seen- Season nine, episode 24/25 After a toxic on-again off-again relationship with Kelly and getting fired from Dunder Mifflin, Ryan appears in the last episode raising a baby on his own. He ditches the baby and runs away with Kelly. Definitely still the same dude.
