Rockstar🎓
Top SchoolEiji Sekiya is a software architect based in San Jose with 11 years of experience building cloud-native systems for autonomous driving and large-scale data platforms. At TIER IV he leads the architecture and technology roadmap for Web.Auto, designing microservice-based SaaS on AWS and coordinating cross-functional partnerships. Previously at DeNA he engineered fleet management, recommendation and game-AI systems and maintained complex Hadoop-era analytics stacks, giving him deep expertise across data infrastructure, ML workflows, and production optimization. He blends hands-on coding in Go, Python and TypeScript with applied research techniques (HMMs, graph convolution, Bayesian methods, reinforcement learning), enabling practical social implementation of data and ML. An Osaka University math-systems master, he is as comfortable designing distributed systems as he is tuning probabilistic models for real-world operations.
