The perfective aspect is not created by changing the ending. There are normally two words for each verb. One is the imperfective, the other is the perfective. Often these two words are closely related, but this is not always the case. (Often the perfective is simply prefixed with “По”). If you look at the conjugated verbs list on this site you can see some examples of how verbs are conjugated in both aspects. Here are some examples of verb pairs.
(Imperfective, Perfective)
Жить, Прожить - live
Любить, Полюбить - love
Делать, Сделать - do, make
Говорить, Сказать - talk, speak, say.
Работать, Поработать - work
