Top SchoolSang Chun is a Senior Data Scientist based in Seoul with 13 years of experience building end-to-end ML and distributed computing solutions for enterprise-scale data. He has driven production systems and model improvements at companies from CJ CheilJedang BIO—where he integrated HPC, Kubernetes, Spark and GPUs and delivered patent-pending applied ML—to e-commerce at Wider Planet and now Coupang. His background blends deep computational biology research (PhD, University of Michigan) with hands-on engineering: feature-space reduction on Spark/BigQuery pipelines, ALBERT/BERT text classifiers on multi-GPU clusters, and automation that cut delivery times by ~95%. Known for mentoring and translating complex science for non-technical stakeholders, he pairs rigorous experimental validation with pragmatic software practices to move models from prototype to production.
