About Me
I’m Ray Li, a CS and Math junior at NYU passionate about building smart, practical systems. I’ve worked on everything from deploying local LLMs for private financial insights to formal verification and symbolic computation in Lean. I enjoy combining theory with real-world impact—whether it’s writing fast backend code, designing AI-powered tools, or doing quant-style analysis. I’ve interned as an SDE, published research, and love solving hard problems with clean solutions.
