Hello, I'm Stefanie — Hà Phương

If you want to know more about my journey, please visit this autobiography.


Me in a nutshell

I'm studying Math and Computer Science (Class of 2029) at Pomona College in Claremont, CA.

Right now, I'm interested in the intersection of pure math and practical ML/AI, with a soft spot for computer vision. Outside of research and coursework, I also just love building quirky, spontaneous projects simply for the fun of making things work.

If you want to yap or want to talk about anything, write to me !

Things I've built

Phở-Around

in progress · optimization, mip, llm, fastapi, react

A web-based itinerary planner that frames city wandering as an orienteering optimization problem. Powered by a PuLP/CBC mixed-integer linear solver, bilingual (EN/VI) schema-constrained LLM parsing, and a React 19 + FastAPI backend with offline travel-time routing.

Ham Chơi

published · film, photography, web

My film-camera side project. This is a small web home for the rolls I shoot: scans, captions, and the stories between frames. A documentary of a wandering kid, one frame at a time.

P-resents

published · algorithms, next.js, tailwind

A gift-exchange planner built on bipartite matching: generates optimized rule sets from group traits, cutting manual matching time by 90%. Next.js + Tailwind, with RESTful APIs and secure authentication flows. This project is part of the P-ai club.


What I'm thinking about

[Working title] On exact recovery of binary signals from incomplete Fourier data

publication coming soon!

How Much Real Data? Training-Data Composition for Sim-to-Real Visual Navigation on a Low-Cost Robot

publication coming soon!


Off the clock

Everything on misc happens outside of work and research, and still shapes how I build things.
