Hello Hugo! You write well, but there are a few mistakes.

First notebook entry: Introducing myself

My name is Hugo and I would (Because it is something you hope to do, but is not certain) like to improve my english because I want a job in IT.
I studied Telematics Engineering (Capitalize titles.) and I graduated last year.
I like reading classical literature and listening to muzic like rock in English/Spanish.

Great job, and keep practicing! :)

Well done for your first post Hugo!  Always make sure that you capitalize names of languages, countries, professions.  In your second sentence  there was no need to repeat "I" as it was already understood you were the subject of the sentence.

Try and write a longer post next time to give yourself more practice.
