but depends what you're trying to convey.

A is interesting too, the best of the options that rely on your initials.

C is the most distinctive, though I think the angles of the lines could be tweaked; the space on the left of the slash creates an odd space with the left bracket.

Typewise, I like the sans serif in option C, but maybe pairing it with a serif font for the smaller 'web design' copy.

One stray thought: the way you've drawn the "<" almost looks like a C. You could take the aesthetic from option C, make a J out of the basic bracket shape, and flip that into a CCJ logo, too.
