Yeojun Han

Software Engineer in AI Tooling

About

I'm a software engineer focused on AI tooling on the Visual Studio Copilot team at Microsoft. I studied Computer Science at the University of British Columbia, where I also worked as a teaching assistant for Computer Vision, Applied Machine Learning, and Software Construction courses.

I've worked at Microsoft across Visual Studio Copilot and Azure SDK, as well as at Ansys on OpticStudio and HCI research at UBC's SOCIUS Lab.

When I'm not coding, I keep myself active by traveling, going rock climbing, surfing, and making pottery. I'm also an ex-AA soccer player who runs sometimes.
