Can you review my branding ?

Hello developers , hello designers !

I'm currently working on my website and I have designed a logo and multiples banner for my branding / artistic direction.

Can you tell me what do think about these ?

The speech :

I went with blue and purple because they are my favourite colours and the white/black / are pulled from blue and purple !
I looked on Duckduckgo for icons that everyone can understand are code.
I found many images like this one:

I figured if I made a logo like this one, I could be understood by everyone !

I also wanted to create a logo I can use everywhere, modern and if possible with my nickname inside.

Recap:

Constraints of the logo:

• With blue
• With purple
• For everywhere (website , social media )
• Modern
• Include an icon, banners and full logo
• With my nickname

The logos:

The icon:

Designed with 2 colours and the shape of <>.

The full logo:

Designed with the icon, it makes CAMARM DEV, my pseudonym

Banners:

I also designed banners for opengraph and social medias:

The classic:

Full logo in a rounded white rectangle.

The logo background:

Full logo with description and a background full of the icon.

The abstract background:

Full logo with description and a background full of abstract shapes.
