Jae Jeon is a software engineer with 13 years of experience, currently building scalable systems at Google after multi-year backend and recommender work at Kakao. Trained in computer science with an M.S. focused on Human-Computer Interaction from Seoul National University, he combines rigorous academic grounding with production engineering instincts. He began as a Ruby on Rails backend developer powering KakaoStyle and later moved into recommender systems, giving him a blend of web service and ML-adjacent experience. At Google he applies that cross-domain expertise to large-scale, user-facing systems in a Seoul-based engineering role. Colleagues appreciate his ability to translate HCI-informed user needs into robust backend designs and recommendation logic. Fluent in shipping reliable services, he quietly bridges research-minded thinking and pragmatic implementation.
