Download CV or Hire Me ?

Hey there!! what's more professional in an portfolio website to have an hire me button or a simple download resume option. which one should be there?
* also is it advisable to use particle.js in portfolio website front page? (professionally)?

I liked your website so much clean UI and a good readme file and tells a lot about the project itself.
Amazing work!!
I've made an portfolio website if someone can give me some improvement suggestions it would really help me :)
