Need some help making my application better

So I started my junior year, and I'm gonna go for the Fall '28 intake in the US universities as an international student.

Computer Science probably with more focus on AI (still looking at the courses)

I have worked extensive in machine learning, and have two research papers under my name (both in reputed journals), and a few good projects.

However I still feel like my application is not enough to get into the best programs, so I wanted to know what else I could do.

I know even with a perfect resume there will be a lot of uncertainty, but I want to do my best.
