Presentation

Hi, my name is Carlos. I'm writing this presentation because I want that someone to help me with the grammar, and especially, where I have to put commas. So, I'm 21 years old and my hobbies are playing soccer, listening to music, and playing on my laptop. I'm studying civil engineering and I would like to improve my English to have more possibilities to study or work abroad. I really appreciate anyone who can help me correcting this message. Thank you.

Bye

Carlos, the comma that I highlighted in blue after "listening to music" is not necessary, but I included the correction because you mentioned your interest in learning correct comma usage. That type of comma usage is known as the Oxford Comma. You can do more research or message me for a more in-depth explaination if you wish.
