Summary
👤
Senior🎓
Top SchoolKenji Matsuoka is a backend engineer in San Francisco with over a decade of hands-on experience building scalable data and cloud systems and more than twenty years in software and engineering roles. He has led architecture and DevOps decisions at companies from Alexa Internet to Monolith, where he was the first software hire in an R&D data team and helped move compute into the cloud to accelerate a novel low‑emissions carbon black process. Comfortable bridging domains, he collaborates directly with chemical and mechanical engineers to build production data pipelines and deploy ML models. His background combines industrial-scale web and data engineering (rearchitecting Alexa’s core pipelines and services) with applied research training—a PhD in computational physics—giving him a strong footing in numerical methods and reproducible engineering. Known for pragmatic technology choices and long-lived, low-maintenance services, he’s as focused on operational reliability as on enabling scientific discovery. Currently advancing backend and cloud work at Luminary Cloud, he brings scientific rigor to product-grade infrastructure.
