Tianyu Chen is a Senior Software Engineer with 11 years of experience, currently building core ML and LLM infrastructure at Google from Sunnyvale. He holds a Master’s from Carnegie Mellon and a top-ranked Mechanical Engineering bachelor’s from Shanghai Jiao Tong University, a background that informs his systems-first approach to complex engineering problems. At Google he has progressed through multiple engineering levels and contributed to Google Health and clinician-facing infrastructure as well as high-throughput ML serving platforms. Tianyu is also an active open-source contributor—his work on GoogleCloudPlatform/esp-v2 improved API key extraction and request filtering within the Envoy-based service proxy used widely for API management. He combines production-grade backend engineering with research-facing experience from CMU, making him comfortable bridging prototype ML work and scalable production systems. Colleagues describe him as pragmatic, detail-oriented, and adept at translating academic rigor into reliable, real-world services.
