Projects
OpenGL/OpenCL Particle System
|C++, OpenGL 4.1, OpenCL 1.2, GLFW, GLAD, ImGui, CMakeJan 2026 – Mar 2026
- ▸Architected a GPU-accelerated particle simulation using OpenGL/OpenCL interop, sharing VBO memory directly across compute and graphics pipelines to eliminate CPU-GPU data transfers.
- ▸Migrated a legacy GLUT/GLEW/GLUI codebase to GLFW, GLAD, and ImGui, achieving full cross-platform support across Windows, macOS (core profile), and Linux.
- ▸Implemented OpenCL compute kernels to fully parallelize particle physics on the GPU, including velocity integration, gravity simulation, and sphere collision response.
- ▸Targeted OpenGL 4.1 core and OpenCL 1.2 to maximize hardware compatibility across all three platforms, including Apple Silicon and legacy GPUs.
- ▸Authored technical documentation adopted as a final portfolio project for Oregon State University's Parallel Programming course.
6S Auditing App
|Vite, React, PHP, SQLJun 2025 – Aug 2025
- ▸Delivered a full-stack auditing system with authentication, admin controls, and a cross-division KPI dashboard for department, company, and sister-site visibility.
- ▸Integrated data prefill from prior audits and linked records to minimize input, with autosave, validation, and image upload/cropping for streamlined reviews.
- ▸Enabled scheduling of future audits with automatic reminders and workflows optimized for first-time users.
- ▸Formulated a responsive design to ensure full functionality and ease of use on both desktop and mobile.
ULX-Reverse: Mouse Configuration Tool
|Rust, libusb, WiresharkAug 2024 – Sep 2024
- ▸Reverse engineered proprietary mouse firmware through USB protocol analysis using Wireshark.
- ▸Developed a cross-platform CLI application using Rust and libusb, achieving full functionality in 300KB.
- ▸Enhanced functionality by implementing custom DPI profiles with shareable configuration codes.
- ▸Designed a platform-agnostic solution compatible with Windows, MacOS, and Linux operating systems.
BigShell: POSIX-like Shell Implementation
|C, Unix Process API, LinuxMar 2024 – May 2024
- ▸Developed a POSIX-like shell program, demonstrating proficiency in low-level systems programming.
- ▸Implemented process management using Unix API, including forking, job control, and signal handling.
- ▸Designed I/O redirection and command pipelines, applying OS and memory management concepts.
- ▸Created custom shell utilities with dynamic variable expansion.
Full-Stack SPA with NEON Database
|Next.js, React.js, Node.js, TypeScript, shadcnJan 2024 – Mar 2024
- ▸Led the development of a full-stack application utilizing NEON serverless database and Next.js.
- ▸Collaborated with a teammate to design the database schema for efficient data storage and retrieval.
- ▸Integrated CRUD methods for managing player and team information, along with automatic calculations.
- ▸Leveraged Next.js for server-side rendering and performant database access via Vercel Edge Functions.
Mouse Fix Program
|C++, Qt 6 Widgets, Windows.hJan 2024
- ▸Built a Mouse Fix Program that reduced mouse input lag by 20% and improved movement consistency.
- ▸Designed a registry editor with extensive error handling, simplifying advanced mouse customizations.
- ▸Constructed a modern Qt 6 interface and easy-to-reverse customizations.
- ▸Incorporated object-oriented principles to ensure modularity, scalability, and maintainability.
