About Me

Hello! My name is Paul Andrew Sullivan, but I go by Andrew. I'm a junior Computer Science and Engineering student at the University of Iowa whose passion is building and tinkering.

I've always enjoyed learning how things work and improving them — from constructing with Legos as a kid to assembling my first custom PC in 8th grade. Over the years I've become the default IT consultant for family and friends, building custom systems and solving real-world tech problems.

My drive for problem-solving led me to pursue CS&E, blending my love of creation with engineering discipline.
