Correção para izzie: Hi, I am Aline

Meu nome é Aline. Tenho 40 anos. Sou publicitária, mas não trabalho mais como anúncios. Eu sou servidora pública há 15 anos. Eu amo meu trabalho. É gratificante ajudar as pessoas.
No meu tempo livre, eu gosto de passear com as minhas cachorras, estudar sobre nutrição e vida saudável e assistir Netflix.

I've been a civil servant for 15 years, I love my job and it´s rewarding to help people. In my free time, I like to go for a walk with my dogs, study healthy life and nutrition and watch Netflix.

It´s not much of a correction, more like a change in the choice of words and some tinkering with punctuation.
I hope this helps.

I tried to keep it as informal as possible. A more formal approach (say, to a job interview) you should focus on the work life and facts, which would make you take out some of the "free time" activities, since your hiring manager/hiring person could think you as a person with more focus on things you do outside of the office, more of a leisure time. But to a presentation to the peer colleagues at the class or (not to interview jobs, etc) it´s okay.
I hope this helps.
