UH Umer Hammad

I'm Umer, a rising junior studying Computer Science and Math at DePauw University. Most of college so far has been about learning to build things that actually work, not just things that look good in a demo.

I've taught coding to over 100 students across two different programs and co-founded an NGO that runs food drives and works with orphanages. Outside of code I care way too much about mechanical keyboards, read a lot of fiction, go on long runs, and type fast enough that it's become a personality trait at this point. Feel free to reach out, I like talking to people about what they're building.
