Nancy Chen
Full-Stack Developer · CS @ Columbia

I build products that feel intuitive up front, and run on carefully engineered systems behind the scenes.

I’m Liuyi (Nancy) Chen, a full-stack software engineer working across React/TypeScript, backend APIs, and Python/ML to ship reliable, user-loved applications.

About

I like building software that’s clear to users and clean to maintain. I’ve worked across the stack: React interfaces, backend APIs, Python pipelines, and LLM integrations.

Product-minded engineering

UX clarity, thoughtful systems, and measurable impact when shipping.

Across the stack

React/TypeScript + APIs + data flows + automation for real workflows.

Research-to-build

From HCI and maker communities to multimodal models and datasets.
