Summary
👤
Senior🎓
Top SchoolSeonghan Ryu is an LLM and NLU expert with over a decade of hands-on experience building production-grade dialogue systems, lightweight language models, and LLM-based AI agents. Holding a Ph.D. in Computer Science and Engineering, he has led NLU efforts across Hyundai, Samsung, and 42dot—shipping on-device assistants, enterprise chatbots, NL2API/NL2SQL tooling, RAG pipelines, and function-calling agent routers. He combines deep research roots (dialogue management, out-of-domain detection, reinforcement learning) with practical software engineering in Python, Java, and C++, enabling high-performance, deployable solutions. Now leading LLM understanding at 42dot, he focuses on scalable agent orchestration and lightweight embeddings while keeping a pragmatic eye on efficient fine-tuning and on-device constraints. An interesting thread through his career is translating academic dialogue research into customer-facing systems for automotive and consumer products.
