Hi! I'm Grace Jin and I Like Making Things

Computer Science + AI '27 @ Cornell University

I like creating beautiful user-focused systems, systems-level software engineering, and computer graphics. p.s. click around

Incoming Software Engineer Intern @ LinkedIn. Prev. Software Engineer Intern @ Cepton. Co-Founder of Cornell XR Project Team. Please hire me I want to make more cool software.

Shader Programming!
i like visually-appealing stuff! (to be fair, who doesn't)

Projects

COOLER RAY TRACER BUT IN PYTHON

A CPU-based ray tracer in Python. Tried to render on multiple cores (with ProcessPoolExecutor) and killed my potato laptop a few times but worth it. Initially we complained because using Python is inherently so slow but we realize it is much more easy to debug and do math, which was more of the emphasis for this course anyways. Therefore, thank god this project was in Python. This project also has cool texture mapping, glass refraction, and BVH acceleration. Built for Cornell's CS 4620. It is still a very cool project, and it got the top grade in the class!

Tech Stack: Python, Blender

NEUROSCENT: MIT REALITY HACK WINNER

Inspired by a research paper, I collaborated with a team of 5 to create Neuroscent, a system connecting VR brain-computer interfaces with olfactory displays to promote users' mental well-being based on biofeedback. Used OpenBCI's Galea ($30k) BCI VR Headset connected to Unity with a dynamic interactive environment based off of detected alpha brain waves. Basically, hands-free exploration in a Unity Enviornment that I designed and coded up from scratch. Trying to turn this into a cross-university project right now!

Tech Stack: C#, Unity, OpenBCI software, Blender, Arduino

GRAPHICS RASTERIZER: CUSTOM RENDERING MY 3D MODELS

WORK IN PROGRESS: I want to learn more deeply how OpenGL works by writing a simplified clone and suffering through the learning process.

Tech Stack: C++

RAY TRACER FROM SCRATCH BUT IN CUDA

WORK IN PROGRESS: With no external libraries, and certainly no graphics libraries, I'm making my own ray tracer to learn more about graphics and create cool renders for my projects.

Tech Stack: C++, CUDA

ZOODINI: GAME BUILT WITH JAVA AND LIBGDX

Made for a game design class, I worked with a team of 7 to make a stealth game centered around a stray cat and octopus to present at Cornell's GDIAC showcase. From the UI to the game features. all of it was made on the LibGDX Java-based game engine.

Tech Stack: 100% JAVA!!

Showcase and Play!

PHYSICS XR FOR CORNELL'S PHYSICS DEPARTMENT

Building visualizations of EM Waves, Gaussian Surfaces, and multiple other models with Unity and C# to help students visualize otherwise invisible electromagnetism concepts. Built in collaboration with Cornell's Physics department for 400 students, with 800+ plays.

Tech Stack: Unity, C#

Deployed Project

WEBSITE FOR CORNELL SPACE SYSTEMS DESIGN STUDIO

I built a website to inform a general, curious audience about Sailing to the Stars' July, 2025 launch to space. Website was featured in the Cornell Chronicle! The bulk of the website was built and deployed the last two days before it made it into the Cornell Chronicle. I personally recruited the web designer and the co-developer for the website. Thanks guys!

Here's the Website!

Here's The Devlog Behind the Scenes!

PERSONAL WEBSITE

Built with Javascript and Three.js with WebGL shader code, HTML, CSS. There is a naive solving algorithm that I am working on for the cube right now, but some steps are backtracked in the wrong direction right now (see if you can find it in action!). Working on debugging this!
