Bo Yang is an AI Training Infrastructure Engineer with 14 years of experience building production-grade ML and systems software from the ground up. He splits his time between research and engineering—maintaining popular open-source projects (3k+ stars) and publishing in deep learning and functional programming while architecting serverless LLM platforms and multi-agent systems in production. At startups and companies like Tacnode, Gradient, and Meta he owned end-to-end LLMOps/MLOps, CI/CD, and observability for elastic, multi-tenant inference and fine-tuning services, even enabling test-time training via Discord integrations. His deep systems and compiler background shows through contributions to major projects such as the Scala compiler, Ammonite, shapeless and HHVM, reflecting expertise in performance, language tooling, and backend reliability. Based in Palo Alto, he excels at turning ambiguous requirements into repeatable best practices for novel AI infrastructure. Colleagues rely on him to bridge low-level performance engineering with pragmatic AI architectures that scale.
