About

Hi nice to meet you I'm Preston!I'm a 3rd year Systems Design Engineer at the University of Waterloo. I have a background in building large payment systems and am super interested in fintech. I believe engineers should have as much product knowledge as PMs and always keep my users in mind when building customer-facing software.I'm open to backend and infrastructure SWE roles for Fall 2026 and Summer 2027. Would love to chat!
