Did you use recruiters or apply direct. Being new to the field recruiters could be very useful in trying to sell you to their client and give cv tips.

I also suggest apply to fewer targeted companies and tailor your cv to their job spec. Staying honest of course!

Also learn technologies that are easier to market albeit less fun such as Java, JS and C#.

Get a friend who is in the industry to review your cv or attend meet ups and get people there to have a look and give honest feedback.

Having a blog, a github and giving talks would help too.
