Umer Hammad | Software Engineer

I'm Umer, a junior studying Computer Science with a minor in Mathematics 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.
