Here’s my Personal portfolio http://codepen.io/bhattmayur1987/full/dprNjX/. Please provide your feedback
The design is quite neat 
I think you missed this.
User Story: I can see thumbnail images of different projects the portfolio creator has built (if you haven’t built any websites before, use placeholders.)
On mobile consider reducing the size of the headings. You can do so with media queries. Also consider adding some text-shadow to the text in the About section. It becomes hard to read against the sky in the background image.
