Hi, I'm Preston Williams

When I'm not coding, you'll find me in the gym, gaming with friends, watching sports, or hunting down new food spots to try.

Who I am

About

I'm a Computer Science student at Cornell University's College of Engineering, graduating December 2027. I'm passionate about building reliable software, from trading systems and distributed backends to ML pipelines and mobile apps.

I've interned at Datadog and been a fellow at Jane Street, and I contribute across Cornell Data Science, Cornell AppDev, Capra Group, and Cornell Cup Robotics.

Based in Bronx, NY. U.S. Citizen. Reach me at ipw5@cornell.edu.
