Hello! I'm Tianyi Ding.
A full-stack software engineer based in Sydney, focused on building practical web applications, business workflow systems, and AI-enabled products. In my professional work, I build and maintain enterprise applications using C#, ASP.NET, SQL Server, RESTful APIs, authentication and authorization, database design, and secure backend services.
I also build full-stack personal projects with React, TypeScript, Node.js, NestJS, PostgreSQL, Docker, and cloud deployment. I enjoy taking ideas from early product thinking through API design, frontend implementation, testing, deployment, and iteration.
I bring a background in AI and data science, with hands-on experience in RAG workflows, LLM integration, AI agents, document search, and applied data-driven systems. I learn quickly, work well with complex open-ended problems, and like turning technical ideas into usable software.
