Ethan Yu
AI Full-Stack Architect
About
Engineer with seven years of experience, including two years continuously creating and delivering 0-to-1 AI projects and new business lines, from direction validation and prototyping to core feature delivery and stable launches. I work well in uncertain product contexts and fast-changing technical environments, turning product goals into verifiable and shippable engineering plans.
My experience spans frontend architecture, AI engineering, streaming rendering, cloud sandboxes, agent workflows, and backend development with Golang and Node.js. I care about product judgment and engineering quality, balancing user experience, system reliability, and long-term maintainability during fast iteration.
