Is it a terminal Master's that you would be applying to?
Your GPA looks ok and obviously the higher it is the better. However, the more important thing that adcomms consider if your research experience and potential. Your research experience will help you a lot. Now, if it's a terminal master's then perhaps this won't be such an important factor, and other factors such as your Statement of Purpose and your letters of recommendation will be more important. I would definitely encourage you to get more internship and research experience that will lead to strong recommendation letters. Applications at top schools are competitive, but I think you're on your way.
Here's a document from a Stanford MS (I believe that Stanford's MS is terminal), that highlights the admissions process:

All the best!
