Available to hire
Hi, I’m Yuewei, a software developer studying Computational Mathematics at the University of Waterloo, graduating in May 2026. Over the past few years I’ve spent about 20 months in full-time internships, building real products as a full-stack/software engineer instead of just classroom projects. I’ve worked across backend APIs, databases, and modern frontends, and I’m comfortable owning a feature from idea to production and debugging it when things break. I stand out from many new grads because I already know how to work in real codebases, ship on deadlines, and communicate clearly with teammates and clients.
