ReDesign of Freelance Web Designer Portfolio

I am a freelancer. I recently re-designed my own portfolio website. Please have a look: http://www.echofreelance.com/

As a freelancer I choose a flat style for my new web design. This means I removed stylistic characters such as drop shadows, gradients, textures, and any other type of design that is meant to make the element feel three-dimensional.

I would love to receive feedback on how I can further improve the design and other aspects which will lead to a better conversion rate.

Thanks!
