Honestly i would like to meet Steve Jobs, iI think he is one of the best inventors and designers of all time.

I´m an advertising and digital marketing student, and iI want to focus on UX and UI design, so that´s why he is a reference for me, iguru to me. I like how he revolutionateised the world with his products and the way he thought.

If iI could meet him and hadve a conversation, iI willould ask him a lot of things about how can iI improve my skills and be a better professional.

Remember that the word “I” is always capitalized
Although in some informal cases like texting, it’s acceptable to just write “i”

1. “Reference” doesn’t make sense here. It would make sense if you said you were taking inspiration from his work, but in this case words like “role model” or “idol” work better.
2. This last sentence should be written in the present simple tense. For this tense, just add “s” to the end of the verbs, and “es” to verbs ending in e for verbs referring to the she/he/it pronouns
Normal Example: Walks, talks, eats, sleeps
“Es” Example: Writes, hopes, takes, revolutionizes
For any other pronouns (You, I, they, we, etc.), you wouldn’t change the verb and all and would simply keep it as is
Example: “I walk”
3. While “products” works fine, the word “inventions” fits better.

1. For this sentence, we’d use the second conditional tense, which is used to describe hypothetical or un-real situations in the present or future. So we would change words like “can” and “will” to “could” and “would”. These words however are the only words to have a “ould” ending in the tense along with “should” (That I can think of). For any other verbs. I’m not the best explainer of this tense and I’m not entirely sure if I got everything right, so I recommend you research the second conditional tense
2. We would use “become” instead of “be”. This is the present perfect tense. The best way I can think to describe this is if you ask a little kid what they want to be when they grow up. You’d probably get an answer like “I want to be a firefighter.” So that kid wants to BECOME a firefighter in the future. It’s a bit confusing, even I’m having trouble explaining it, it might be best for you to research this aswell.
3. You don’t need to use the word “better” here as it makes the sentence sound odd. A professional is the best of the best, it doesn’t get much better, so you’d just say “how I can become a professional”.

Honestly i, I would like to meet Steve Jobs, i think. Personally, he is one of the best inventors (and designers) of all time.

I´m an advertising and digital marketing student, and i. Currently, I want to focus on UX and UI design, so that´s why he is a reference for m. Therefore, Jobs is inspiring to me. For instance, iI like how he revolutionateized the world with his products and the way heof thoughtinking.

If i could meet him and hadve a conversation, iI willould ask him a lot of things about how can iquestions on how to improve my skills and become a better professional.

The sentence was a run-on sentence (a sentence that is grammatically too long). I thought it flowed nicely as two separate sentences. However, you could have them as one sentence if you connected them with a word like "because":

I put "That's why he is a reference for me" at the end just for clarity.

I believe you were looking for the word revolutionized.

If iI could meet him and hadve a conversation, iI willould ask him a lot of things about how can iI could improve my skills and be a better professional.

Had a conversation is past tense, you would have a conversation.

When you are talking about things that are hypothetical (not real), you use words like could and would instead of can and will.
When you say "I will ask him things", it sounds like you will actually be talking with Steve Jobs. This is a hypothetical scenario so you "would ask him things (if you could)".
