Seoul, South Korea
Summary
🤩
RockstarSang Park is Head of LLM Engineering based in Seoul with over a decade of hands-on experience building and optimizing large language models and NLP systems across industry leaders like Hyundai and Kakao. He combines deep systems programming (C++/CUDA, Python, Java/Kotlin) with practical GPU expertise, having run LLM training and inference at SuperPOD scale (up to 40 nodes / 320 GPUs / ~49k GPU hours). His work spans the full LLM lifecycle—from production-grade inference and optimization to pioneering training runs that produced a 1.3B open-source model—while also improving Korean NLP services such as KakaoTalk’s semantic similarity engine. A pragmatic leader and contributor, he has applied algorithmic rigor to open-source algorithm problem-solving on GitHub and consistently moves research into reliable, high-performance production systems.
