About me

At work, I focused on research, fine-tuning, and experimentation with the OpenAI API and open-source models. Outside of work, I engaged in study projects and prototype development, participating in competitions and academic paper submissions. My main interest lies in exploring how AI can function as a companion through human interaction and what combinations of elements enable such meaningful experiences.

회사 내에서는 OpenAI API와 공개 모델의 조사, 튜닝, 그리고 실험 중심의 업무를 수행하였고, 외부적으로는 개인적 흥미를 기반으로 스터디를 진행하거나 프로토타입을 제작하여 공모전 및 논문 투고 활동을 병행하였습니다. 특히, AI가 사람과 상호작용 속에서 동반자처럼 기능하기 위해 어떤 요소들이 결합해야 하는지, 그리고 이러한 조합이 어떻게 의미 있는 경험으로 이어질 수 있는지에 대해 관심이 많습니다.
