Niu Du / AI builder

I build things with AI.

I build practical software and AI systems that turn complex scientific and clinical workflows into reliable products, with close attention to the people and decisions they support. On the side, I make things that are useful and fun, from apps to open-source developer tools. A few are below; my enterprise experience is in my portfolio.
