software engineer, open-source contributor and AI researcher

I love researching, designing, building, and contributing. I care deeply about making things better for both people and machines by questioning assumptions, finding different ways to solve problems, and understanding how things work at a fundamental level.

You can find me on GitHub and @felixlu1018, or reach me by email.
