If you are interested in landing a web developer front end job, you can start by developing some utility websites as part of your portfolio. Should you succeed to learn framweworks like React.js/Backbone.js + html 5 + basic java,sql. I think you could definitely land the job.

However, if I was you I would have continued in embedded SW and tried my hands on Arduino, Python, c++ and tried in another such job. As it would have allowed me to progress on what I have already learned.

But it depends on you, what motivates and interests you between the 2.
