Wilson Xie

I'm a 3rd-year pursuing Applied Mathematics BS minoring in Computer Science at UC Santa Cruz. This past summer, I interned at Amazon as a Software Development Engineer on the Payments Processing team.

Also an avid competitive programmer on Codeforces and Leetcode.

In the ICPC 2023 season, my team representing UC Santa Cruz advanced to the North American Championship at University of Central Florida, Orlando, where we finished 33rd rank.
