Recommended Resume for fixed income

Hi guys, I am from Brazil and would like to work in US with Fixed Income. As I am in the 3rd year of college (major in finance/economics), I am asking for advices for get a good resume in the next year to get a interview.

Nowdays, on my CV, I had a intership at a investiment boutique in Philadelphia, PA and currently I am working on a Association which is the pricing maker of fixed income in Brazil. I also was a business director of a junior company. Finally, I was the teaching assistant of Excel with VBA in my University, having a class of 50 people.

About technical skills, I can use MIcrosoft Office with VBA, Bloomberg, Capital IQ, and I have some knowlodge of R and Matlab.

What else do you think that I can learn to improve my CV?
I have found that some analysts in Fixed Income sector can use C, C++ and SQL. Where can I get some materials to learn those programming languages?

Thank you in advanced,

Tiago Junqueira.
