You have very interesting EC’s. Just FYI, our HS has had 3 students admitted to Tufts in the last two years. None of the 3 were in the top 10% of their class, and at least two had slightly lower GPA’s than does the OP. But all 3 had strong EC’s, 2200+ SAT’s, and demonstrated interest. I’m sure they all wrote very good essays and had strong LOR’s too. One applied ED, one was a legacy RD and one was a regular RD.
