I’m an AI engineer at Upstage. I build AI agents for document work.

Previously, I worked on automating evals for Solar, Upstage’s foundation model. I also built a chat engine for SIU:, a member of MAVE:, a virtual K-pop idol group.

Before joining Upstage, I trained models at Silvia Health to detect cognitive impairment from speech recorded on mobile devices.

During my master’s degree, I used active learning to make emotion recognition more data-efficient. I also created K-EmoCon, a multimodal biosignal dataset for emotion recognition.

When I’m away from my laptop, I enjoy climbing, boxing, meditation, and time with my family.
