Professional Bio
I am a theoretical
physicist by training (B.Sc. from the University of Sรฃo Paulo;
M.Sc. en route; Ph.D. from Stony Brook University; graduate research at Los
Alamos National Laboratory and Brookhaven National Laboratory; and undergraduate
research at NASA Goddard Space Flight Center) and a principal
software engineer by trade (Shopify, Apple, Etsy, Yelp,
startups, and private projects, both as an individual contributor and in
leadership roles). Although I have deep expertise in several fields, I'm a proud
generalist and systems thinker, and perhaps my greatest strengths lie in
building fast, architecting creative solutions, and tackling new and challenging
problems.
I started coding in middle school, and over nearly three decades of uninterrupted work in engineering and science, I've worked on a wide range of problems. My story with AI/ML began back in high school, when I won first place in a national competition with an Expert Systems project (โAI Doctorโ); continued during my Ph.D., when I wrote my thesis on the equation of state of neutron stars at Los Alamos (I also took graduate courses in ML and robotics during that time); and carried on through many moments throughout my engineering career.
For the years ahead, I am building NULLSTAR, coming in 2027 for real friends. I hope you'll join me then!
