If you've got a solid background in backend, I suggest you to monitor your local job postings every day.
Also follow on Linkedin and built up the connections with ICO organizators.
There's a huge chance to get a great job, because crypto is hottest topic of 2017.
Just try being social and communicate with relevant people. Show what you can offer, that's my 5 cents.
You'll build up your skills during the work instead of courses and other theoretic stuff.
