Not only drinko I love drinking it, I also really love to make it, w. We have a professional coffee machine at home, so I ha've mastered how to make coffee.

When I was a kid, my family didn't allow me to drink coffee in order to provide my health, abecause of health concerns. At least i, that was their opinion.

But since I know cofffe I lovedrink it, I enjoy it, so their prevention was only valid forin my childhood.

My interest had grew up for making and rightfor making coffee has grown, and now I can sureconfidently say that I have the almost the same knowledge as a Barista.

I love coffee so much that I can drink up to 4 incups a day.

Even though I know what you mean, the sentence does sound more natural if you specify how much coffee you're drinking. That is, 4 CUPS. But in spoken English you will definitely hear people say things like "Do you want a coffee?" or "I'm going to buy a coffee".

Not only drinko I drink it, but I also really love to make it. At home, we have a professinal coffee machine at homefor professional baristas, and so I have mastered how to make real coffee.

"Professional coffee machine" doesn't sound quite right here.
The word professional is normally used to describe a paid person rather than an amateur. E.G. Amateur actor vs. professional actor.

When I was a kid my family didn't allow me tolet me drink coffee in order to provide my health, at least it was their opinionbecause, in their opinion, it was bad for my health.

In general, it's "improve my health" rather than "provide my health". "Provide my health" doesn't make sense in English.

But since I know cofffe I love it so their prevention was only valid for mythey were only able to prevent me from drinking it while I was a childhood.

Not completely sure what you were trying to say here.

My interest had grew up for making and right now I can surely sayAnd later on, I grew to love to make it. I am confident in my coffee-making skills and believe that I almost have the almost same knowledge as a Bbarista.

Professions aren't capitalised unless they're part of a title or name.
E.g. "I got into a fight with Doctor James." Because "doctor" is part of a title/name, you capitalise it.
But alternatively you could say, "I got into a fight with the doctor," or "I got into a fight with the barista."
