About Me
Hi, I'm Eliyahu
I'm a computer science student at Brooklyn College. Most of my time goes into building full-stack apps and competing in cybersecurity CTFs and hackathons.
I'm mainly focused on XPStrength right now, a gamified fitness app I've been building since freshman year. I'm running an IRB-approved study on it to see if gamification actually improves workout adherence. On the side, I do hackathons for fun and the challenge of building a full-stack app under a strict time constraint.
