Hi, I’m Zhangwenchi Li, a software development engineer-in-training currently pursuing an MEng in Computing and Software (Co-op) at McMaster University in Canada. I enjoy building both frontend and backend systems with a data-driven mindset, and I’m comfortable working with React, Next.js, Node.js, NestJS, Spring Boot, and cloud tooling. I’m especially drawn to SSR optimizations, reusable component design, and improving product performance through thoughtful, pragmatic engineering. Previously I interned at Shopee in Beijing, contributed to Shopee’s A/B test platform with 25+ features, built a reusable table column configuration component, implemented a DOM export tool, migrated pages to a Next.js-based codebase with SSR, and created an email notification module. I also contributed to Python tooling like Eelbrain and led backend work on campus marketplace projects, focusing on authentication, caching, and robust API design.…Hi, I’m Zhangwenchi Li, a software development engineer-in-training currently pursuing an MEng in Computing and Software (Co-op) at McMaster University in Canada.
