Christopher Cho
I'm a full-stack engineer currently at Wayfair, where I work on checkout, loyalty, and rewards. Lately I've been focused on making high-traffic flows faster and more reliable — and building tools that help the team ship quicker. Mostly working with React, Next.js, TypeScript, Java, and GraphQL.
