Weimeng Ding

Full-Stack Developer building web, mobile, and AI-enabled systems

I build practical software across web, mobile, and backend systems, with a focus on reliability, real-time workflows, and maintainable architecture.

My work spans React, React Native, TypeScript, Node.js, .NET, and Python, covering both product-facing features and internal operational systems.

This site is a long-lived personal system for projects, experience, technical writing, and how I think through engineering decisions.
