About

A quick snapshot of what I’m focused on and how I like to work.

I'm a Computer Science student focused on building thoughtful, high-quality software that solves real problems. I enjoy taking ideas from concept to implementation, designing clean user experiences, writing maintainable code, and iterating based on feedback. I'm especially interested in full-stack development and applied AI, and I'm always looking to learn and improve through challenging projects.
