About Yujiang Wu

I’m a machine learning engineer with a deep focus on building end-to-end intelligent systems that work — from raw signal ingestion to reliable deployment.At John Deere, I led two high-impact projects: A sensor-less temperature estimation system for electric machines, combining deep learning and CAN decoding on a cloud+edge pipeline;🧠 An LLM-powered AI assistant to scale internal expertise, accelerate onboarding, and reduce debugging friction.I build systems not just to deliver results — but to establish long-term leverage, reproducibility, and ownership.I thrive at the intersection of AI, systems architecture, and product thinking, and I’m always seeking ways to turn core insights into scalable platforms.Let’s talk if you’re building something that matters, and need someone who can turn complex ML logic into deployable, trusted infrastructure
