Where are you from?
You are highly qualified, but you fall into the dreaded Asian male STEM subgroup, which is notoriously difficult. If you are from California (as seems likely from the OP), it will be even worse:
Almost all of your ECs are STEM-related, so you seem a bit narrow in terms of your focus. What is there about you that will distinguish your application from all the Asian male STEM applicants with similarly ridiculous (or better) credentials?
UCB should be close to a sure thing for you if you are applying in-state, but otherwise you have a bit of an uphill climb to make yourself stand out.
Also, Stanford EA is restricted, so technically you cannot also apply EA to Caltech and MIT if you go that route.
