Hello, I'm Francisco! I'm a mathematician interested in solving meaningful problems that make the world a better place.

In my free time I enjoy reading, building small machines, tinkering with software, learn obscure skills, facilitate meandering philosophical conversations, debate, take pictures, draw, and dabble with 3D.

Connect with me if you'd like to learn more.
