You can always ask for more, the worst thing that can happen is that they say "No". I would suggest you put together a list of successful projects and tasks you have worked on and present that to your manager with an ask for a raise. Make your case that you have demonstrated value and think your compensation should better reflect your value. I don't know where you are in the world, but where I am (in Pittsburgh, PA, USA) a jr dev with 1 year of experience and a good track record could ask for $20-25/hr without issue. You also don't mention what work you have been doing, that can change the money equation a lot. Negotiation is a difficult skill to learn, but it can be very rewarding. Good Luck.
