Jeff Dai

I'm a freshman studying CS and Engineering Sciences at Harvard University. I love building at the intersection of manufacturing/hardware and frontier software.

I am currently optimizing for learning, for how best to build with people and teams I admire, and for problems worth solving.

I have experience across varied areas, including quantitative trading, research, robotics, AI engineering, and industrial CNC machinery.

I like reading, writing and music.
