Looks like a good start compared to what I used to make when I first started

I always try to give design tips

From my view, I take it that the social media icons and skills in the middle are a sort of carousel that rotates? If not, I would maybe balance their sizing as it seems to suggest that to me. But that's my personal view.
Also your #CSS is quite faded into the background and is harder to see which might obscure some people from clicking it and seeing examples (if that's your intent).
Your head is nice, I like the wavy design but the grey wave does get flat on the right-hand side, is that so you can left-align the image and keep it flowing right? If not I'd recommend making the right-hand side grey part curve upward back towards the yellow.
I also think your header is a nice use of flat, pastel colours, and so the fade from the services #WEBDEVELOPER etc is maybe unbalancing that theme just a bit.
I don't read Italian, but if your design motto or slogan is the two sentences at the bottom, they could be a deeper grey like the header wave to make them pop - draw attention to what makes you talented, make it more bold in colour

Keep up the good work!
