Profile building tips.

Hi,

I am Indian female, 23 working in a leading IT firm for last 2 years. I have completed my engineering from a top college of Mumbai. My GPA is around 3.0.

Now the big question:
What should I do to add things on my profile. I wish to get into one of the top 50 b-schools in the world and will be applying next year. I want to pursue finance for a change in job profile and because of my keen interest. My GMAT score is 720.

At the moment, apart from my job, I have lead some of the events conducted by the ‘Corporate Social Responsibility’ society at my company.
I volunteer at an NGO that educates underprivileged kids.
I have lead and volunteered some events while in college.
I am trained in martial arts and have a brown belt.
I have done some microsoft certifications in dot net.
I have some certifications in finances from NSE (National Stock Exchange, Mumbai)

I have a year or so before applying. Please suggest what I can do.
I am planning to learn a new language. Also I plan to complete my CFA level 1. I think its never late to start, with your guidance I can work harder to make a good profile and increase my chances to get a good college and inch closer towards my dream.

Awaiting your reply.
