About Me

Hi, I am Yiyang You, and you can call me Kevin. I recently completed my B.Sc. at the University of Toronto, double majoring in Computer Science and Statistics with a minor in Mathematics.

I enjoy turning technical uncertainty into shipped systems: production APIs, data pipelines, AI agents, dashboards, and interactive web experiences. My recent work spans LLM-based physics simulation workflows, museum web applications, retail analytics, and logistics systems.

  • 2+ years of full-stack and backend development experience
  • Java, Python, JavaScript/TypeScript, C/C++, R, SQL
  • Spring Boot, Django, React, Node.js, Docker, AWS, PostgreSQL, MySQL, MongoDB
