About
I’m Sion (Paul) Jeon, an undergraduate at the University of Toronto studying Mathematics and Computer Science. I enjoy building practical software and AI systems end-to-end—turning messy real-world problems into reliable tools, whether that’s automating workflows for hundreds of users or creating computer vision models that perform well on benchmarks.
I’ve shipped projects across web development, data-driven applications, and multi-agent AI, with hands-on experience deploying solutions on cloud infrastructure and integrating tools like email/calendar, knowledge retrieval, and structured data pipelines. I’m also a teaching assistant and a school LMS support assistant, which has strengthened my communication and problem-solving skills when helping others learn and use technology effectively.
