Thanks for writing in, and congratulations on an excellent GMAT score. Indeed your biggest challenge will be standing out in the "Asian-American engineer" pool, where your competing peers will also likely have high GMAT score. There are a few tools you have to help achieve this differentiation:
1) Your community service involvement seems strong and an important part of who you are. Hopefully you can leverage this experience to focus on one of your essays, rather than just talking about work.
2) Achievements at work. Try and emphasize anecdotes that show leadership, upward trajectory, and demonstrate personal maturity.
3) Your goal statement. You'll want to make sure this is very well-defined. How do you plan to rely on your analytic background to be a cloud computing consultant? How will an MBA help you achieve this? And how will you make the leap from consulting to charity work in China, or is that always going to be a side project? If so, explain the role it will have in your life.
