I don’t see you as unlikely for most UCs. Unless I’m misreading, your UW UC GPA is 4.0. You’re a plausible candidate at any UC; UCLA and UCB are reaches, because the acceptance rates are so low, especially for engineering, but I’d be surprised if you didn’t get into one or more of UCSD, UCSB, UCD, UCI. I wouldn’t bet on which without knowing more (and UCs are predictably unpredictable). You’ll get into UCM, almost certainly UCR, likely UCSC.
