Rockstar🎓
Top SchoolSeoyoung Ko is a Senior Machine Learning Engineer based in Austin with eight years of experience building production-grade cloud and ML systems, currently focused on real-time fraud detection at Visa. She combines strong backend and infra expertise from roles at Samsung and IoTeX—where she contributed to the iotex-core blockchain by refactoring storage layers and improving test coverage—with privacy engineering research at CMU and PwC. Her work spans scalable streaming pipelines (FlinkSQL), Kubernetes/EKS operations, and low-latency model inference for high TPS environments. She has hands-on cryptography and blockchain experience (including a published staking-architecture paper) and a growing focus on privacy-preserving AI and synthetic time-series evaluation. Comfortable bridging research and production, she brings an uncommon mix of privacy-first thinking, distributed systems engineering, and open-source collaboration to applied ML problems.
