Top SchoolHyogeun Oh is a Machine Learning Engineer with 7 years of experience focused on MLOps, Kubernetes-based AI infrastructure, and high-performance LLM serving. He has architected production-grade distributed training and serving systems—implementing GPU Direct RDMA, MIG, Triton, and a Model Context Protocol (MCP) to boost scalability and stability in enterprise and air-gapped environments. Hyogeun blends deep performance tuning (vLLM optimizations, speculative decoding, prefix-aware caching) with practical reliability work such as Prometheus/Redis/SSE observability and CI/CD automation that frees teams to focus on core problems. He values trust and predictability, sharing schedules transparently and building repeatable pipelines to minimize operational risk. An active community contributor and communicator, he runs a tech blog with 1,500+ MAU, spoke at PyCon Korea 2025, and participates in numerous study groups. Based in Seoul, he pairs academic research experience (SCI(E) Q1 publications) with hands-on engineering to squeeze peak performance from constrained resources.
