Software Engineer | Graphics Enthusiast | Alien
Hello, I’m Arrian! I’m a software engineer who interested in optimization, graphics, C++ and artificial intelligence.
Scroll down to see cool projects I’ve worked on!
Projects
Last of Sus
A simulation of a fungal zombie apocalypse in Unity; utilizes behavior trees, boiding, AI pathing, and L-systems
Nature Scene
A scene of a japanese garden lake with some quirks, implemented with numerous animation algorithms
Aurora Blast
For the UCLA/UCSB SnowJam, our team of 6 students created a 2D platformer in Unreal Engine 5.
Raytracing in One Weekend Project
A very simple ray tracer based on the first book of the Raytracing in One Weekend book series. Although it works, it’s pretty slow because it runs on the CPU… maybe… just maybe… some improvements will be made in the future.
Excellent interface
I managed a group of 6 students to work on a web app that facilitates the reading/writing to a Fuseki knowledge base with Excel files. I primarily worked on the frontend of the application (first time using React.JS) and integrated the frontend and backend together.
GLBoids
Throughout my undergraduate career, I’ve been saying that I wanted to multithread something in games. Again, hello world, MULTITHREADING BOIDS! And among other things
New Gen Home Gen
In my Game AI class, our group made an AI living room generator that employs genetic algorithms and constraint validations in its generation mechanism. I was in charge of setting up the core logic, the renderer, and some of the constraints.
Unreal Boids
In preparation for an interview, I wanted to try out how different Unreal was to Unity. I created a boid simulation in Unreal as a hello world project.
Shadertoy
My fascinations for graphics has brought me to play around with shaders in shadertoy. You can find the first one I reverse engineered here!
One Last Job
My final senior capstone project. Worked with 4 game design students to create a 2d wild-west themed bullet hell game. I designed and crafted an extensive AI behavior tree system for the enemies and allies of this game.
Godot
As I used Godot (an open-source game engine), I found some issues I would like fixed. So I contributed to Godot (and open source) for the first time. And I still am!
60 Second Alchemist
With a group of 9 game design students, we developed a prototype of a 3D platformer in Unity. Play as Hazel who must harvest ingredients and brew potions for customers to make a living.
My Soul Is Yours
On a team of 9 game design students, we developed prototype of a grid-based turn-based rpg about a cult leader boy raiding a castle with his followers. I was in charge of creating the grid logic as well as the enemy unit AI logic.
The Amazing Clown Girl
A blocky clown girl implemented using WEBGL and javascript
Stop the Music
With a group of 8 game design students, we developed a prototype of an audio experience using Unity and FMOD. Players swat gremlins playing instruments to prevent them from summoning their leader.
Depresso
For my final project for a generative design class, our team of 3 game design students developed a maze generator with procedurally generated elements.
Blood Thirst
A simulation of bats. Behaviors implemented include flocking, starvation, homing, and death.
Miao’s Mission: Cat Food Frenzy!
I worked with 2 game design students on a puzzle platformer game about a alien catgirl collecting. I oversaw most of the programming and implementation of platforms and physics.
Mole Rush
I worked on a endless runner about a mole with 2 game design students. This was the first game I ever published.
Experience
Streamlined user interfaces by optimizing hot paths
- Abstracted a map entity querying feature of Call of Duty’s level editor into a tool with using C++, Imgui, Windows API
- Applied feedback from mentors concerning modern C++ features, memory optimizations, and clean code style practices
- Incurred 10000% performance speedup compared to original tool, using multi-threading and data oriented paradigms
- Communicated extensively with graphics team to parameterize and implement QoL features for debug lightmap viewer
- Utilized DirectX12 compute shaders to debug frustum culling and LOD culling system, improving frame rate by 1600%
Tutored for an undergraduate compiler course of 80+ students
Responsibilities included:
- Organizing 2 hour office hours on a semi-weekly basis (although I arrange extra)
- Providing answers for both technical and conceptual problems
- Reporting back to the professor on collective student progression in the course
- I also went out of my way to help grade the exams
Graded for an graduate compiler course of 20+ students while auditing
Responsibilities included:
- Writing scripts to help run student code submissions and find errors
- Developing keys for grading exams
Tutored/graded for an undergraduate compiler course of 60+ students
Responsibilities included:
- Reading and running tests on student code submissions
- Developing keys for grading exams
- Running 2 hour office hours on a semi-weekly basis
