About me

Data Science student at the University of Michigan who gravitates toward the intersection of technology and design.

I'm drawn to building things that are clear, thoughtful, and genuinely useful. I enjoy the process of taking an idea, understanding the people it's for, and shaping it into something that feels intuitive to use.

Outside of data and design, I love to travel and document the moments that shape how I see the world. I'm always experimenting with new crafts, from tactile ones like crocheting to digital projects on Procreate. If I'm not making something, I'm probably just catching up on a favorite series.

Projects

I build

01 / Full Stack Engineering

Redpen

A Word add-in bringing AI-powered review, rewriting, simplification, and templating into a lawyer's live document, built around an independent suggested-changes engine that separates "the AI thinks this should change" from "the document changes."

02 / Systems & Infrastructure

AI Harness

A native iOS app connected to a self-hosted backend I run on AWS, which routes conversations to language models and streams answers back in real time. The foundation of a system I'm actively continuing to build on.
