Rockstar🎓
Top SchoolDohyun Kim is a Machine Learning Engineer with 14 years of software experience, currently improving recommendation and multimodal search systems at Bucketplace using Python, TensorFlow, PyTorch, Go, Spark, and Airflow. He has a strong applied ML background from Samsung Research, where he built object-detection models for robotics (vacuum cleaners), and a track record of shipping production media and streaming features at NAVER and LINE. Dohyun blends research-minded modeling (metric learning, multimodal architectures) with pragmatic systems work—optimizing pipelines, inference, and data workflows for real products. His open-source contributions include Bluetooth stack fixes to Samsung’s widely used TizenFX, reflecting low-level systems fluency beyond typical ML roles. A Hanyang University software engineering graduate with a 3.8 GPA, he is comfortable spanning from device APIs to scalable ML services and improving reliability at every layer.
