About Me

Based in Chicago, IL, I’m a full-stack software engineer who loves turning tough ideas into products people actually use — and notice only because they work.

I recently earned a B.S. in Computer Engineering from the University of Illinois at Urbana-Champaign (May 2025). Over the past two years I’ve shipped AI chatbots, full-stack dashboards, and iOS features during consecutive internships at AbbVie, boosting chatbot answer-rate accuracy to 95% and trimming report sizes by 25%.

Comfortable in Python, TypeScript, Swift, C++, and more, I move fluidly between backend logic and pixel-perfect front-ends, always chasing the cleanest path from problem to polished solution.
