"I've become a rollback on April 7th, 2015." - In this case you should've used Past Simple instead of Present Perfect Simple, because we don't use this tense when we say the exact date :P If you still want to use Present Perfect Simple, then replace it by "I've been a rollback since April 7th, 2015". This is only a tip, don't take it as insult, I just love grammar :)
