Hi, my name is Guanhua Ding and I am a detail-oriented backend software engineer with over 7 years of experience building production APIs, event-driven architectures, and distributed services. Across Leonardo.Ai and Canva I have shipped end-to-end generative-AI pipelines, cross-platform SSO authentication, and enterprise admin backends using Java and TypeScript/Node.js. I work AI-first, pairing coding agents with strict specification design, automated testing, and code review.
