Salary increase negotiation software developer

Hi everyone, I don't know if this is the right place to make this post.
I want advice from other software developers.

One year ago I was hired from a company as junior android developer. Then I had 1.5 year of experience on android development and 3,5 years on the industry.

When I started I had a senior college android developer who did code reviews on me and I learned a lot from him.
Unfortunately, that lasted only for three months, because the company split and I was left alone.
Since then I performed quite well. I added a lot new features, I solved bugs, PIs, I took big part application`s refactoring etc. I never missed a deadline.

In few weeks we are going to have evaluations. Would it be too much If I ask for 30% increase?
my responsibilities increased a lot, I have anyone to guide me, or review my work and cover my ass.

what do you think ?
